I think because makecode thinks “targetsHitOrScore” has a bad word in it.

We can look at the project if you send the link. Usually this happens when it runs out of memory, perhaps due to something that you have saved with the settings extension causing your code to take up a lot of memory. Maybe try deleting all saved settings by putting that one block for deleting all settings into the OnStart.

I thought saving too much with settings caused panic code 921

Only the link stops working if there is a bad word. The whole sim doesn’t stop running lol that would be really really annoying
