To Reproduce

Set up MISS with an array of about 55 double chests. Fill several of the chests with items. Run MISS and then exit it. While saving the chest index there should be a too-long-without-yielding error.

This does not happen on CC:T 1.100.6. I have not tested with a fresh setup on CC:R but I will when I get home.

Can't recreate that locally, could you upload world with this issue? miss.cache_index set to true

could you share screenshots of this??

update: this appears to be an issue specifically with chests from the Fabric version of Iron Chests.

Removing the Diamond Chest I had in the array fixed this issue.
