I am playing on singleplayer 1.16.1 survival PC and I'm not getting any experience. I have been playing for a while but for some reason, I haven't been getting experience. When I kill a mob or when I'm mining, I don't get anything. I don't understand what's happening. I used to play on 1.16 optifine, then I tried just forge with a pvp mod and optifine, then I just did a regular 1.16 version and none of it works. I have restarted my game multiple times and nothing has happened.
What mods do you have installed? I might be able to find out why. Otherwise could you say give me a save/those mods and zip them up to make it easier as it might be with a particular version of the mods, or it might be Forge causing it and with them zipped up I can pinpoint the mods quicker instead of guessing which ones it might be and that it might have be a bug, been fixed or is an issue with particular mods.
