i have managed to fix the issue with
by Opening JcInventoryPawnInterface and editing something, compiling, saving, chaining it back then saving and compiling. This interface has two functions but is used pretty much by every single UMG widget. I still have transient issues and can not save the blueprint here
here is my new compile log,
and this one was from my saved/log.log
also another one of my widgets will not save (it is used as a child in JCWItemSlotContainer, so there’s defiantly a pattern)
This one does not give a Engine/Transient error.
