epoch conflict with infistar

[lordacus]

so i have been making a server between trying to get my provider to update their mods section. after getting this don i found the server with epoch and infistar were conflicting each other such as: when joining i can use infistar but when i press f9 or i to enter my inventory or f10 for the mobile pad it then conflicts (i think) infistar and i can no longer use it. any ideas on how to stop this
