I have a bit of a weird bug that I stumbled onto.
The studio that I work at would like to jump to Houdini 21. I've set up all our envs to read all of our olts same as always.
Everything reads in fine. I've I have the verbosity switched on I can see no errors.

In houdini obj level I can drop down nodes as usual. But when i switch to solaris any of our previously created hdas wont read in at all.

Traceback (most recent call last):

hou.OperationFailed: The attempted operation failed.
Invalid node name

The weird thing is that i can still drop the node with python, without any issue
hou.node('/stage').createNode('tf_env_lightrig')

The only thing that i can vaguely see in the error message is that its got an extra lop_ in the name in the error
Tool::TF::lop_tf_env_lightrig::0.0.2

Does anyone have anything that could point me in a direction?
