Someone help me fix this piece of shit

[ShadowHunterDaPro]

are you using a resource pack?
if so try disabling it, it could be outdated

Speaking of which, there also has been a lot of lag lately on MCP, RushPvP, and the Hub. I don't know if this is just the "Fires", like Silas was talking about, or if its just my computer. Im mostly getting a lot of delay lag, mostly from chat, and a little bit of block glitch lag. After a few seconds of this lag, it kicks me, saying "Timeout Exception: Null". Or something like that. I mostly just remember the "Exception: Null" part (my mom took the comp so i cant check atm). I tried doing a lot of things to try and fix this, but nothing seemed to work, and I was trying to think of what's been different lately, and then I thought of the Custom Texture pack that the server uses. I just recently started using the pack, and I've been having this lag problem ever since. Someone please help me.
