Why do GSE macros "Lock up" sometimes?

Sometimes ill have my gse macro running, look down and notice abilites are not firing. Spamming key and nothing is happening; Drop Combat doesnt help.

What does help is swapping to a totally different GSE macro instead.

Anyone know what causes this? Anyone Else experience it?

depending on the macro usually its locking up because a spell cant fire in a sequence for some reason … look in the macro for the /castsequence … look for a spender spell and thats the one usually locking it up
