I have 3 demos where this happens. For at least one it does not happen always. When the bug is triggered radius has a very high value, e.g. radius=2.79508645e+20 (like above) or radius=3.0478225e+32. |

In CTransportCAI::AllowedCommand 4 parameters are read for both commands CMD_UNLOAD_UNIT and CMD_UNLOAD_UNITS. In case of CMD_UNLOAD_UNIT this will lead to read garbage from the heap as this command only has 3 parameters. Added example widget to trigger the bug. |
