I have experianced a problem. I am not sure if it deals with the planeset (you can see the zepplin is stuck) or if it is the patch itself. A helicopter class arcraft is trapped on an oil rig (The zepplin in the planeset behaves like a helicopter and thus is a helicopter class). I cannot stop the aircraft nor send it to the depot. The downside to being trapped is that it is costing me money every second that zepplin/helicopter is stuck on an oil rig.
I am getting a feeling that this can also happen on helipads to

.
The only way to fix this problem is to destroy the oil rig and/or the helipad in order to free it. I have no problem destroying and rebuilding a helipad but I do have a problem destroying an oil rig because it's expensive to destroy it and to rebuild it and that alone would rapidly drain my funds since there is a chance that the prospectors "cannot find a source of oil".
