Would you consider using a method for the toolbelt-1 problem that consumes less resources? I'm playing a rather large modpack (that includes the armor frames mod) and every time a research is complete the game freezes for about 20 seconds. I love the mod but it gets kind of annoying having to wait 20 seconds every time I want to research something.

The problem seems to be from the armor frames mod. After more testing the issue only occurred when having enabled the armor frames mod, independently of this mod.
