For about a day or so, I was able to join servers in the AOTB modpack. Now every time I try to get on a server I get this error. "The following muliparts are not installed on is client: pr_100v, pr_f100v" Or it will get stuck on this until I cancel it. "Logging in..." If you know how fix this, please help me. -*signed name stolen!*
