New to Blender, new to Blender API development, and not really an expert in Python. Of course, my first self-imposed assignment is to migrate a rather dubious plugin from 2.79 to 2.80, go figure.
(Long uninteresting story about contortions to make this work deleted).
So, I got an addon with a couple of modules in a zip file. It works fine, but when I need to make changes, I create a new zip, remove the old addon using the Preferences dialog, and install the revised version, and somehow Blender won’t take my changes.
A telling behaviour is that if I make a mistake and I fix it, in the Blender console I get old error (but shows the new code in the trace).
I tried removing all contents from the %appdata%\Blender Foundation\Blender\2.82\scripts\addons\__pycache__ folder to no avail.
Just restarting Blender causes the changes to be activated. Anybody else has this issue? Is there a workaround?
