Cannot move Vehicles

[Zamrod]

I get errors whenever I try to drag a vehicle with Conditional Visibility enabled. The vehicle doesn't move on my screen but its vision circle does. After that, I can no longer move the vehicle. After I refresh, the token is at its destination.
Foundry 0.7.9
DnD5e 1.2.4
Conditional Visibility 0.1.4

The errors are as follows:
