Server keeps crashing

A friend and I are making a server and for the past week it’s been going good. Then all of a sudden it started crashing.

We got this error message:

Could this be whats causing the crashing?

The “GetNWInt” is part of the problem, it should be changed to “GetNWString”, but your server will still crash either way until a GMod patch is released to fix all the things the update broke.

Wait until a patch is released
(Probably never)
