Modpack version
1.72

The first time I logged into the game after updating to 1.72, I ran into the following issue:
p455w0rd/p455w0rds-Library#52

This might have been a case of bad luck because logging in a second time was fine, so this probably has nothing to do with version 1.72 in particular. It might be an idea tough to disable the setting B:EnableShaders in p455w0rdsLib.cfg as mentioned in the issue.

Thanks, I've updated the config :)
