No longer works on PF1E

[araknophobia]

As in title. Was working in my PF1E game up until last week. Now I no longer see it in the available modules section, even though I see that it is installed via the Foundry setup screen.

Edit: Foundry version 9, Build 280
PF1E version 0.81.3

Edit 2: Reverted to version 0.4.1 for now, which seems to work normally.
