So a few players like me, jblocker and some other guy named legit lost our Gil. It happened twice for me and jblocker. I lost 20k each time I lost my Gil. jblocker lost 50k and then 20k. Legit lost 150k. I'm guessing that there's a bug with the economy plugin. I hope you fix this, Typhoon.
Also, it seems like I can't gain anymore Gil. It stays at 100. Same with jblocker.
