Hey, no apologies necessary, not on you but on their weird design.
That looks... weird and bad, yes.
The slight texture warping has been mentioned once before years ago, so I was sort of aware it was a possibility (back then), but that was it. The completely offset stuff is definitely not intended, and needs investigation.
Feel free to send me a Cohost Ask with part of your map (or link to a google drive that has it or something if it's too big), and maybe the dimensions for the problem texture(s) so I can generate something appropriate for testing on my end.
Fair warning, my body is doing Bullshit Things again, so I can't promise anything, but I'll _try_ to take a look at it this weekend if I have your stuff.
