Back up your saves and re download the game, then add the mods again. Sometimes modding just breaks stuff(maybe some are conflicting?), its just a part of the process.
I'm on Android as well and have lots of mods, but I've never experienced this issue so I'd assume either the mod was outdated, conflicting with another mod, or maybe there was a mistake made. Either way redownloading the game(and keeping your save!)should work, try adding and testing the mods one at a time so find which of them is the problem. Hope this helps.
