Major FPS drops/server stutters

I am experiencing some major server performance degradation when this plugin is loaded since the April update.. Even when loaded with the lowest possible values in the config (default stack size; 1 per industrial item). I attached my performance graph for reference - it seems to pause the server tick and then you see the FPS drop down to 10 or less periodically. This only happens when this plugin is loaded.

I'm not sure what specifically this does on the backend, now that you have it separated, but for the time being I can't load this at all - it is making the game unplayable.

You most likely have a bugged hopper / conveyor running. This happens sometimes when a conveyor is connected to a hopper in a loop going to oil refinery / furnace. 

An update was pushed that will remove all bugged hoppers / conveyors so whatch console output. 

Additionally the QuickIndustrialPreCheck has been updated to deal with null instances when that happens.

Changed Status from Pending to Fixed

I follow the potential for a bugged conveyor/hopper - is there something specific I need to do to fix it though? I'd prefer not to have to delete all of those assets from the save if possible

Nvm - I didn't realize you meant you pushed an update for this... loaded and monitoring now, thank you for the quick reply

For reference I was able to create a bug with both the hopper & conveyor just by randomly dropping items into a hopper in a small loop with 2 conveyors running items through & an oil-refinery. After an hour of testing I was only able to re-create the hopper bug 2 times & the conveyor bug 1 time due to having to time it just right when dropping something in the hopper while the conveyor is pulling an item from the same attached chest..

Chest > hopper > hoppers out-put to conveyor = bug randomly depending on when stuff is sucked into the hopper.
