Lavender Crawly and Moze (Gunner) mech issue

When using the mech against the Lavender Crawly, 95% of the time I hit the Crawly and it goes flying off the map. Tried with, vanquisher pods/ railgun, railgun / v33 nade launcher , rail gun/ minigun setups all have kicked the Crawly out of the map.

I get the same issue with rocket launchers, shotguns, and the sirens slam. I think its caused by it ragdolling and the game physics going crazy
