Ever since prepatch at random points during heavy play like mythic dungeons or just after a long while of normal play I'll get the error

This usually occurs in combat, shortly after receiving this error whenever using CTRL, SHIFT or ALT to page actionbars, my game freezes for a second due to the flood of lua errors which has caused some deaths mosdef, checking BugGrabber shows me absolutely massive amounts of

Are you getting this one with just Dominos + Domios_Config enabled?

it happens with both, config enabled and not loaded. It paginates a few times until you see the stack overflow error, than paging stops showing. But for me at least shortcuts still work

It was perfectly reproducable yesterday, but I was busy playing. Today I wanted to debug, and now the error doesn't happen. Super weird -.-
