I turned this app off and my stack size on inserters went to normal except for stack inserters... i now have those stuck at 1+69 and the others are at 1+2 this is causing issues as that stack size is far to large and it really hurts the use of these when loading assemblers from belts... there are long lags while it picks up 69 items and it waits till its empty to start, making the almost unusable

This will probably cause issues if you turn the mod off on a save after using it (sorry). You can overwrite the pickup size of stack inserters by clicking on them. This was never meant to be 100% balanced and my cause issues with your save if you go overboard with it.
