0001562: Frozen shrubs display incorrectly when the ice melts
I opened a murky pool (without knowing of the explosive water bug), and flooded an area of my fort's land. Next thing I knew, I started seeing some bright-red V's, which claimed to be muddy shrubs. Later, I saw bright-red S's, for saplings, appear, and then T's, trees. These turn only dark red at a Z-level up, instead of turning into blocks.
I would guess flood a woodland above-ground.

explosive water bug?
2010-04-26 19:32   
I'm sorry, I really don't understand how this is a bug.
1. Trees regrow above ground.
2. The colour is different because they are muddy.

... is there anything I'm missing?
2010-04-26 19:44   
(edited on: 2010-04-26 19:45)
Are you playing with any mods? I don't think any trees have 'S' and 'T' in vanilla.

These turn only dark red at a Z-level up, instead of turning into blocks. <- Does this part mean that they display as a dark red 'S' or 'T' from the level above?

2010-04-26 19:48   
Maybe also explain this exploding water bug as I haven't heard of it.
2010-04-26 20:02   
"explosive water bug" probably refers to 0000190. Don't get hung up on it, as it's not the focus of this report.
2010-04-26 20:05   
Oh, just never heard of it being referred as being explosive water.

Anyways, sounds like a few screenshots will clear things up here.
2010-04-29 00:38   
Aescula, we really could use some screenshots, a save, or other clarification for this one.
2010-05-06 14:02   
This isn't explosive water, and I don't know how to upload screenshots to here.

The plants are aboveground, and muddy. Instead of green, white, brown, yellow, etc, they are a bright red. Instead of ♣, ♠, and the like, they are S's for saplings, and T's for Trees, and bushes aren't a ", they're a V.

These cannot be collected or chopped down.

I have no mods whatsoever, I haven't figured it out yet.

Does this bug persist if you transfer your save into a freshly downloaded vanilla install of 31.03?

What kind of trees are they? (i.e. what do you see when you 'k' over them)

You can upload screenshots to http://tinypic.com/. [^]

2010-05-06 14:38   
http://i40.tinypic.com/2h4ygz8.jpg [^]

They are (in blue) "Muddy Shrub", "Muddy dead shrub", "Muddy sapling", and "Tree", in the [k] menu.

Cannot be gathered, cannot be chopped down.

Yeah, that's... different. Do you have a whole bunch of "invalid ID number" errors (or anything else interesting) in your errorlog? Are you using Wine? Can you farm plants, brew drinks or make plant fiber clothes?

2010-05-06 14:54   
I do not have "Invalid ID number" errors. Nothing that looks like it could be this.

I'm using Windows 7 Home Premium.

My farms are epic. All made after this bug began. I have more plant fiber cloth, plants, and booze than I can even stock.

This is a reclaim fort, also, if that matters.
2010-05-06 14:58   
It might have something to do with reclaiming, yeah. You'll probably have to upload a save for this one. http://dffd.wimbli.com/ [^]

Ice causes shubs/trees to lose their data and show up as red "S"s, "T"s, and "V"s when thawed.

^^^ Wow, I had no idea about that, but you're right, it's an old bug. I'll edit the summary of this report accordingly.

# 000665 □ [dwarf mode][flows] (http://www.bay12forums.com/smf/index.php?topic=9354.0 [^]) frozen shrubs display incorrectly upon thaw

Aescula, is ice a plausible factor in this situation?

2010-05-07 21:32   
It is possible. This map freezes in winter, and that flooded area has had... issues. Issues of 2/7 water freezing to an ice wall, and melting to 7/7 water -_- Tempted to make that its own bug. But it's not important now, as the 1/1 water does cause ice floors.

I've just had this occur in a vanilla 34.07
I had a flood trap spring a leak on the ground level, and flooded most of the map; no ice involved.
It was also accompanied by a significant frame rate drop, which has kinda passed.

I suspect this is happening if the water freezes on top of a shrub/sapling and you then save the game - since it doesn't actually see a shrub/sapling on the tile, the plant info object (which keeps track of the plant's species, grow timer, and even a Name as once seen in Elven forest retreats) presumably gets discarded; as a result, when the ice melts it restores the "shrub/sapling" tile but it doesn't actually have a plant definition under it, causing it to show up as a bright red "S" for sapling or "V" for shrub (trees would show as "T").
2014-11-25 16:16   
Saplings, at least, appear to die when encased in ice (and show the proper symbol). Has anyone seen this behavior for shrubs in 0.40.xx?
2017-05-17 15:04   
Confirmed to occur with shrubs in 0.43.05. Saplings survive with their plant information intact, however.
