Alright, let me make it clear what I've done to fix this before "verify files and reinstall".
I verified blockland's files. Nothing wrong.
I uninstalled and reinstalled the game. Copied old addons to the new addons folder. No dice, still froze.
I uninstalled and reinstalled the game. Didn't copy old addons. No dice, still froze.
Other than factory resetting my computer, I've done everything I can.
Alright, now what seems to be the issue?
When I join a server, I get as far as 'Loading Datablocks', then the bar just stops. Chat freezes too. However, I can still move my mouse and cancel out of joining the server. Singleplayer works fine. Help section, what the hell am I doing wrong?
