Arcade: The Arcade used to be taking too much Bandwith and almost caused SEN to reach it's Monthly Bandwith limit so it was disabled. It was a wierd bug that caused the IP adress of SEN to start using SEN's Bandwith.
Armies: Deathknight found a bug where he could sell negative amounts of items to gain negative minerals. It was disabled becasue people started buying negative amounts of items and gaining profits.
Bank: The bank used to be very unfair to the newer members. Older members were gaining over 5,000 minerals per day in the bank while newer members would only gain 5. It was removed due to unfairness.
Raffle: It was considered unfair to give 5000 minerals to one user. It would just give him/her better chances to win the next round so it was removed for unfairness. Raffle was shut down partly because the people who abused the Zerg Pets started donating too much money to the Raffle causing it to become very buggy. (It had negative number of tickets avaliable.)
SEN Lots: It was buggy so it got disabled.
Zerg Pets: Bugs similar to the ones in Armies were found so it had to be shutdown.
NOTE: All bugs weren't minor ones.
Wasn't SEN Lots disabled because it was too intensive on the databases?
Don't remember quite well the issue with SEN Lots.
I thought that there was a bug of some sort...
You can edit the first post if you know what actually happened.
Well, we don't really need this one anymore since I killed off the links.
