Severity *

Medium (Gameplay Limitation): Non-core functionality is impaired, providing a suboptimal but playable experience.

Brief Description *

Attached save has a Cestus 'Mech standing right on top of a Zephyr Hovertank on the melee attack phase. Attempting to target the Zephyr causes an NPE.

The log gives the following error:
