Similar to this issue: Found A Bug Renaming Assets/Variables - Programming & Scripting - Epic Developer Community Forums
But now it have been fixed. only problem is, that when you rename your asset from “myvar” to “MyVar” it doesn’t rename asset in Windows, so physically this asset is still named “myvar”. This can cause some troubles if you’re using Perforce.
This can be avoided if you rename “myvar” to “123”(for example) and then to “MyVar”.
According to Jamie Dale in thread you linked, this is a Windows issue and not one with Editor. Your workaround, however, seems valid since it skips that step. I’m going to mark this as answered for community. Thanks!
