Compiler not updating the new added code, Version 4.26 Preview 7

I am having a problem after updating code. Getting it to actual update after i recompile it.

I have to go clean out 3 folders in my project folder. then i can restart the editor and let it remake everything. Then it will update my newly added code.

Why wont it update with regular recompiles? it use to find <bug?, not sure but this is strange. This started happening yesterday and now today. Running Version 4.26 Preview 7

How this happened is beyond me, but yesterday i added new code and it would not take. The above fix is all i could find to solve it. It keeps loading the old file(that should not be there) and not new ones that updated from the old one. < weird.

Anyone else having this problem?
