I'm going to copy paste my question I posted in the comments of this UI pack as I don't know how often the author even looks at them, and maybe someone using the pack will have an idea for me
"I'm getting a very persistent error when using this UI, I'm getting around 6-8 critical errors throughout the day and I'm having a hard time pin pointing which addon is doing it. The error says something like FModReallocCallback and whatever that is is crashing wow for me. The only LUA error I'm getting (including looking in bugsack) was an error from a plug in in grid so I removed grid and it's still happening. Any ideas? I really like your ui and want to keep using it"
