RuntimeError: spore nodes's inMesh plug is not connected

[Narann]

Repro step:

• Open Maya.
• Load spore plugin.
• Create polySphere (Create/Polygon Primitives/Sphere).
• Open Spore Manager (Spore/Spore Manager).
• Select the sphere and click on the "Create Spore" icon in the Spore Manager.
• In the Spore Manager, right click and do "Delete".
• Select the sphere and click on the "Create Spore" icon in the Spore Manager.
• Crash (see log below).

[dispatcher] : [CRITICAL] - Uncaught exception:

RuntimeError: spore nodes's inMesh plug is not connected

Looks like it's related to sys._global_spore_tracking_dir that keep created items without remove them:

for k, v in sys._global_spore_tracking_dir.iteritems():
    print k, v

Looks like the nodes tracking is not removed from the dict when nodes are removed.

Maya 2018.5, Linux.

Thanks for the repro. As you described the entry was not properly removed from the dict upon node deletion. Should be fixed now.

[Narann]

Thanks @wiremas! I try the fix as soon as possible.

[Narann]

I just tested, this bug is fixed. Thanks again !

I have few other issues but will create separate tickets with repo steps. :)
