So I understand this has already been reported by others, and read the responses you (Tibberium Fusion) wrote that explains what is going on/why we may be experiencing probs, so you don't need to do the same with me. Just want to share that I am too experiencing the issue of Terraria not launching/hanging when attempting to launch my tweak list that is made up of mostly hotkey tweaks (after updating to TT2 2.3.1411.0). Well, 6 of 10 "Miscellaneous" tweaks are hotkey tweaks. Then have Unrestrict Social Slots from the accessory tweaks category.
I read the comments before updating, but once i saw that you have the previous version available for download, I figured i'd give it a try. But as I'm not/wasn't using any tweaks that caused Terraia to crash, i'll just use the previous TT2 version. Lets hope RE-Logic ends their hotfix patches with a semi-decent version that doesn''t leave you with a headache in order to mod.
EDIT: I actually just noticed something and would like to see if you could clarify:
On my pc, i created a folder for TT2 named as the version which shows "2.3.1405.6" but the version that you have posted as the previous TT2 release is "2.3.1405.1" - Is this just something I can ignore or is there maybe some versions in between 2.3.1405.1 and 2.3.1411.0 ?
