Please provide any additional information below.
Some notes:
Cartographer is working fine.
I can use Cartographer Notes fine.
I can use InFlight fine
AddOnLoader works fine
- no errors show up if I am missing any dependencies, so in this case it's safe to assume that I have all dependencies satisfied.
But every login, the error above shows up, as caught by tekErr.
