Exasperated, that's what I am

For some reason, all of my custom spell triggers decided to go on a strike - all of the sudden, none of them are working.

I have no idea what caused this, and I have undone everything that might have caused the problem, disabling negative numbers for example.

Strange thing is, other triggers governing the map, such as unit spawns, are still working perfectly - I think.

It's just the custom spell triggers, it's like all of the sudden, they just died. They were working perfectly before, but are not working now. Not even a simple trigger to create a brief special effect.

Has anyone ever encountered something like this?

Nope, do they stop at any time? or it is like in a specific place?
