when in compose mode, all UI that unlocks the mouse (TMA menu, escape menu, selector tool menu, chest, etc) are shown as completely transparent with no way to see it, i'm pretty sure this is a mod compatibility issue so here is my modlist:

The problem is Immersive intelligence, It's a relatively new mod so it has a lot of bugs. Don't use the newest version, you can use the 0.2.1 version as that still works with TMA's menus. If you go back to using 0.2.1 don't forget to delete the config file for immersive intelligence or it will crash on start up.

note: mrcrayfish's gun mod has been replaced with vic's modern warfare and i have added optifine and more player models
