Hi, the error only happens after the token is swapped (I only tested on the Host). For example, a druid shape changing to a bear. If no token swap, then no error.
"critically awesome essentials and one click druid" has the generic token swapper. Might be better to test on Pathfinder for example because they have a specific extension for 5e.

I did not have a spell token on the map.
I will do more testing on this today with other rule set. I'm sure its something with the generic token swapper but this error was not happening some builds ago and the token swapper has not been updated in a long time.
