Talk to an online admin about resetting houses If none are available. I'm currently working on a safezone so if you need keys let me know when you see me online.

CS:GO has its limitations as its ran on a newer, unstable version of the source engine, and I have my limitations as I am only human.

Houses are reset on a irregular basis
if someone notices the houses are all full, one of the other admins notify a super+ to wipe the houses inactive

I usually wipe homes from inactive players every two weeks.
