Failed to call hook 'OnDispenserGather'

EDIT: Did some digging. This is from wearing a full mining set. I'm assuming that it's to do with miners luck. No items are being given to the player wearing a set, but I think it's spitting these errors out trying to.

I'm unsure of the significance of this, but I noticed that the server FPS went to 1-3 for about 15 seconds, so checked the console to see if I could recognise anything where I saw:

I know there is a save in here, but saving on the server never affects the FPS more than a slight stutter for a microsecond. Since this, I've allowed my server to save numerous times and have manually saved to see if I could rule that out from being the cause.

Again, I don't know if this is actually the cause or if it's even significant, but thought it could be best to report it anyway.

Thanks,
Christopher.

I see the issue. Realistically it shouldn't be dropping your server frames that much though. I will upload the fix in a bit; going to wait and see if any other bugs appear.

Changed Status from Pending to Closed
