opened (creative) inventory

It says that the Iron Brush is not present, which leads me to believe that there is something different causing the issue than just building the CreativeModeTab.
Are all mods working fine without BetterArcheology? It seems like there is an issue with the Item Registration.

I had no issues before I added it. I will check logs
