Alright, so I didn't want to post this in the Server Bugs section, because no one else seems to be affected. Basically, there are about three glitches I want to address, that for some reason only I seem to have. (I just want to know if anyone else has had these, or if they know how to fix it.) All of these glitches came after the 1.13 server update - but I don't think it's the server. 1: 1.13 Sensitivity. Before the 1.13 update, I would always play Creative on 1.12.2. I decide to go onto a Singleplayer world, and test out some 1.13 features. My Sensitivity, which is at 98%, goes wild, and it's as fast as Hyper. I leave, thinking the glitch will go away. Then, the server updates to 1.13, so I join in 1.13. My sensitivity goes wild once again, and I've switched it to 40%, but when I switch versions to join other servers, if I switch to 1.12.2, 40% is way too slow, and 98% is normal again. 2: The chair glitch. This only happens on this server considering it is the only server I play on with the plugin where you can sit in chairs. This doesn't effect much in gameplay, but it certainly is annoying. When I sit in a chair, I can't get my legs to go straight. My legs are facing the left, I move my mouse an inch, and bam, they're facing right. So I'm always the odd one out during selfies, I try to make my legs straight, but I just can't. 3: The music disc. Alright, so I was watching parrots dance with my friend, I decided to play Mall, because parrots usually like that. It played the Disc 11 for me. I decided to play Far, it played Ward. I decided to use the Ward disc, it didn't play at all. My friend was having no trouble, when she played the disc Far (I heard ward), she said she heard the disc Far, which means this probably is only affecting me. Edit: Someone else has this problem as well, apparently they use a Windows computer, and I am on Windows as well. This is most likely a Windows problem, but I'm still open for help.
