Hi @agleontyev, this is a bug that will be fixed in the next release. If you want to fix before the next release, add the following to your psychopy/experiment/_experiment.py file at line 120:
self._compileLoop = True # Must update on every compile else always False after first writeScript
This is fixed in 3.0.0b6 available now
thank you so much ( I am very slow with my responses)
No problem @agleontyev. Btw there are new releases being made regularly, so best to check for most recent release.
