lgm dies in tank

nothing is shooting at me or anything and im just driving and if a pill shoots at me and i get hit with a single hit sometimes my lgm just flat out dies..happens alot when i get hit from behind....

Alright, here is the scoop, I think.

Your lgm isn't fully in the tank is the problem, an easy way to fix that is to have him build something quick, like a road right under you and he will return and be fulling in your tank. I've had it happen before, a glitch with 1.14 which sucks but gotta deal with it...
