I can confirm this. All Banshees have infinite barrier when I come across them...
I have DVD but for me Origin Retail is working...
Same here, Banshees have inf barrier, if you turn off inf shield after a few seconds they start taking damage.
ok heres the way it works (from my experience so dont get mad if im explaining wrong cal this is just how it works for me)
Step 1: hit escape while on foot with guns available.
Step 2: hit backslash key
Step 3: hit escape
Step 4: see you have 9 grenade instead of x value less
Step 4b: do this after almost every throw it resets to the max you can have after first throw (ex. i have a cap of 3 so i throw with the 9 i get 3 again)
Step 4c: Restrain from complaining about this issue.
Let me know if this helps or doesnt
