I have a custom modpack (actually two very similar packs, MCMinersPack and MCMinersPack Lite) in which I added the Hats mod. The Hats mod GUI will not open. (In either modpack)
I believe this is classified as an in game bug. And it happens every time attempted.
When I try to open the GUI, the screen will briefly "blink", that is, the journeymap minimap and such will disappear momentarily as if in preparation for the Hats GUI to open, and then everything goes back to normal. Also, when I kill a mob wearing a hat, I do not get a notification that should pop up telling me that I have unlocked said hat. No crashes actually happen; gameplay is practically just like the Hats mod wasn't installed, except it is.
I've tried the default keybind (H), Changing the keybind, changing all other keybinds in the pack to keys other than H; I've tried googling it but I can't seem to find a close enough related issue. the Hats mod will work in my other modpacks which have it. I've tried using iChunUtil 4.2.2 and 4.2.3. Also the packs have the Morph mod, and it uses iChunUtil, so I've tried it on 0.9.2 and 0.9.3. I am wondering if there is some mod conflict going on; but I don't see what it could be. I've tried comparing the mod lists of both MCMinersPack packs and my other packs which have Hats. I can't seem to find any inconsistencies. The Hats mod and iChunUtil should be up-to-date with the most recent 1.7.10 versions.
The modpacks are created in 1.7.10. I've been using Java 1.8.0 64-bit, and a very recent version of it. (1.8.0_121, to be specific) The versions of the mods in the packs are Hats 4.0.1 and iChunUtil 4.2.3. Also Morph version 0.9.3.
If I have not included important information, please let me know and I will include it. I have tried to comply to the rules.
