This problem wasn't here all the time, I started to noticed it after you first added gate and fence skins. From 3 angles you can place gates perfectly but from one angle you can't. It's not because of mod, same problem when dissable geo placement. Usualy I have to place gates first, then place walls if I want all gates look perfectly!
pls fix this issue!
Also uploading short video you to see this problem!
