When having Essential Commands installed, RightClickHarvest no longer works on our server. Is this a known issue or something I can change to re-enable or would this require an update on the mods end?

Awesome, glad to hear it's working for you. Thanks for the clarification!

Oh sorry, thought I marked this as sovled, I accedentally reset all the configs for my mods when I updated my servers mod list (not really sure how) so when RightClickHarvest was not working (I had not tried with a hoe) I thought this mod was somehow interfearing until I also noticed a few other mod not workijg as rhey were before ans found out all of my modified configeration files where reset. RCH works perfect with this mod installed too.

That is... surprising. What MC, RightClickHarvest, and EC versions are you using?
