i found out that it's some objects in the layout having a similar name to one from the other project
i was finally able to copy and paste by renaming, but then started encountering an issue when i try to run the project and it's just a blank screen. looked at the console log and saw this
i noticed that some functions in the copy/pasted event sheet are getting auto renamed having a number added at the end when there are similarly named ones within the project, but the actions that are calling those functions still have the original name
but the worst of this is if i happen to leave this be and not fix these actions calling the wrong function and then close the project, the c3p file is now corrupted and i can't reopen it
do you happen to know how that can be fixed?
