Multi-Servers Lag

Hey,

I followed the procedure for hosting multi servers on the same exe, but something seems to be going wrong. All my other servers are running fine with no lag, but out of the 4 servers hosted on this one exe all except 1 is giving strange lag. The ping in the servers browser is 999, but in game the ping seems low but frequently you will spike.

I highly doubt this makes a difference (which is why I didn't post in modifications) but the mod of that particular exe is DDrace.

I was wondering if anyone else has had a similar experience, and could give me a suggestion to fix it.

Thanks

EDIT:
Encase someone in the future gets the same problem. It wasn't a server thing, but instead the general Teeworlds settings thing. I donno what was causing it, but it fixed itself after I deleted all my Settings files in Roaming/Teeworlds.
