I'm having some trouble with adding TCon to the Mech & Magic modpack from ATLauncher on MC 1.12.2. I realize you probably can't help troubleshoot too much given it's a modpack, but I'm just trying to narrow it down.
The game doesn't crash, per se; it starts loading *incredibly* slowly. Even more slowly than conventional modded Minecraft. Specifically, it gets to the portion of initialization where JEI indexes everything, and then slows way the hell down. It will index a batch of items (several thousand) and then halt for a few seconds, then resume, then halt, and all the while the RAM usage indicator goes straight to 4gb and then drops back down when it surges through another batch of indexing. Is there some conflict between JEI and TCon? If I remove TCon the modpack loads at normal speed. Would it be worth testing swapping JEI for NEI? I've never had a similar issue on previous versions of MC with TCon, so I'm at a loss here.
I've allocated 4gb for MC to run, as previous modpacks (Resonant Rise, for example) run fine with 4gb. I have more I could allocate, but ATLauncher seems to think that's a bad idea. Again, sorry for bringing a modpack related question to the table, and I'd appreciate any help anyone could offer.
EDIT: Additionally, when it DOES finally load and I spawn into a locally-hosted world, it freezes every few seconds, with the same frequency that it index/freezes during initialization.
