Already commented on another thread, but I promise I won't keep bugging you.
Unable to take off successfully with Raven from Raven mod while a robo tank is placed down anywhere on the map. Error message included Robo tank in it so posting error message here.

It was apparently fixed, as stated in the other thread, but I still get the error. I am defiantly on the latest mod version, and on latest 0.16 stable. Any help?

I can't reproduce any problems with Raven 0.1.3 and RoboTank 0.3.1. Please post the exact error message along with a screenshot (if possible) showing your setup. Also please check if the problem happens with just those two mods or any other mods are also needed to cause the problem.
