RA 1.48 + patch 3?
I didn't notice any problems with firing gauntlets in large number before.
Below is video from MP session where player's Udaloy launched 22-24 Gauntlets missiles.
Its from friend replay because i forgot to uncheck "read only" attribute from replay.dat
Currently Bergamini is bugged (fix will be added in new version) but Udaloy works fine. Nobody report problems with firing gauntles.
Can you share your mission?
I can test it myself and make video from it.
