After one of the last updates my well got an ugly bug:

I thought everyone had this and it would be fixed in the next update, but it looks like it's not been pointed out in the bug section, and the updates didn't fix it.
I find it really strange because it's obiviously a problem in the model, some vertexes have lost information and now they're scattered randomly, that's why I'm perplexed about the fact that not every well is like this!
