Summary0001562: Frozen shrubs display incorrectly when the ice melts
DescriptionI 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.
Steps To ReproduceI would guess flood a woodland above-ground.

explosive water bug?

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?

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?

Maybe also explain this exploding water bug as I haven't heard of it.

"explosive water bug" probably refers to 0000190. Don't get hung up on it, as it's not the focus of this report.

Oh, just never heard of it being referred as being explosive water.

Anyways, sounds like a few screenshots will clear things up here.

Aescula, we really could use some screenshots, a save, or other clarification for this one.

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/. [^]

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?

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.

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?
(0006392)
Aescula

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").

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?

Confirmed to occur with shrubs in 0.43.05. Saplings survive with their plant information intact, however.
