I have the weather2 mod version 2.3.13, Minecraft version 1.10.2 on a server. This is the only mod installed on the server. Everything works fine until I place a tornado siren. As soon as it starts to go off the server cashes saying "the state engine was in an incorrect state". When I use the mod in single player this doesn't happen. If there is any info about this you know (i.e. what it means, how to fix it) please let me know.

There is also generally more lag. On my laptop with 4 GB RAM with Minecraft 1.7.10 there is almost no lag. On my gaming PC with 8 GB RAM running 1.10.2 there is extreme lag.

Now fixed with commit 0de207e

New build pushed to server.

Going to close this issue, please make a new issue if you notice significant performance issues still, interested to hear about that.
