The charging sound effects for the Lancer in first person view aren't properly synchronized with each actual charge level; you can fire a level 3 charge shot before the actual 'level 3 charge reached' sound effect is played. This makes it more difficult to gauge when to release a charged shot, unless you were already familiar with the Lancer's charging speed prior to this bug occurring.
I forgot to mention that the Vortex (the VS MAX equivalent to the Lancer) also has similar sound timing issues at the moment.
