Reason: Continuation of previous warning - Banned for 1 week (3rd warning still) Admin: gammajon Stamp: 2017-01-20 19:49:55
The 3rd and 4th warn are actually the same warn, so you really have 3. I can only assume that perhaps GammaJon forgot to add the punishment that was put in place for the 3rd warn, and since there is no way to edit an already placed warn, he had to do a 4th "warn" that explained the situation if another player was to look it up. So rest assured, that you still only have 3 warns, just that the 3rd one was split into 2 /warns.
