Try this is solo (same happens in multiplayer) :
- As TSH, shield assault for a tiny bit
- Swap to assault and use your personal
- You will get only like half of personal shield
This bug happens also when you are shielded by half. If you activate personal , you iwll get only like 1/4th extra shield, not full.
It is game breaking, because when assault is really low and Tech sgt. Starts to shield him and assault pops his Personal to safe himself and let medic Heal, he will recieve only half shield and will most likely die.
