"Error merging mods: Copy is out of bounds. Note that this could leave your game in an unplayable state"

[MapMappening]

Doing ANYTHING that involves having to remerge mods brings this message up, telling me it didn't merge correctly. I have all the prereq's installed and freshly installed it, but nothing will get rid of that message.

Technical explanation: You have a mod that contains a file that tries to point to data with a pointer that isn't representable by the data type.

English explanation: One of your mods is broken.

I'd assume it's one that's already installed. You could clear your BCMLData folder (which you set in the settings) to uninstall all mods and install them again.

Odd, PS4 UI Complete doesn't show any comments under it's page that has trouble trying to install the BNP version with this specific problem, but I always do without fail. I even tried the 'Upgrade BNP' option and it gave me the same result. This also happens with other mods I had no trouble installing before, but now do.

This always means that one or more mod(s) is simply broken, either bad yaz0 compression or something that should be yaz0 compressed is not.
