If one upgrades their wp4 through the use of coins, the game will respond with the freezing of the shock wave flash. Now one can still upgrade their weps through the experience they gain from that weps partaking.
I'm gonna try it again and see what happens... I thought it was just my computer lagging, but then I saw this thread.
I just upgraded Pinger and Cats and Dogs. Worked just fine. Dunno what's happening to you two. Sorry. EDIT: For some reason I noticed that when I use sunburst (and only sunburst) in battle the weapon XP doesn't go up.
Same is happening to me!!!!wait ....i dont have it . But still anyone tried upgradring today a weapon NOT from pack 4 and got the error?
This is a bug that's been around for a while, I've had it glitch on me. When I got a bunch of coins, I did this with Wep pack 3 (upgrade 2 weps from it, one wep from normal). Freezes. It will do it with the normal non-pack weps as well, however. But if you wait a day or two, and try again, it will usually work. And yes, it happened to me with Wep pack 4 as well.
It's an odd glitch, how it does that. Work one day, not the next. It's a pain in the ass, if you ask me.
Don't count on it being fixed, unless it's been posted by KChamp that it's fixed. (I haven't been anywhere to know if he has yet) This is most likely just a reprieve from the glitch.
