(Unsolved) External events error keeps happening

I notice this keeps happening when I sometimes edit external events. So I have to close out tof GDevelop when it happens.

It keeps happening with my “Enemy Logic” external events. There’s A LOT of events, to the point where it has trouble loading all of them.

To make it less cluttered, I’m trying to make a finite state machine, where each enemy has it’s own set of external events, and then link those events in the enemy logic external events. and then link the enemy logic to each level it’s needed in. (To keep things neat, and for performance reasons)

The first error happened when when I was creating alternate events, so I deleted the obsolete events i made before, and it suddenly had the error.

The second error happened when I was trying to cut & paste some events into its dedicated external events sheet.

I held shift and clicked all the events associated with the enemy, and right clicked, and selected “cut”, and the error suddenly happened.

I didn’t lose any data. I reopened GDevelop and it was working fine. But I want this to stop.

What should I do?

UPDATE 1: I noticed there’s a chance that this error happens when I delete an event.

UPDATE 2: Even though I outsourced almost all the events for each enemy to external event sheets, the error still keeps happening when I try to delete any events. It’s happening with the “Enemy Logic” sheet specificly…
