How2bugs 101:
1) Confirm that you can repeat it reasonably well.
2) Isolate the minimum actions needed to reproduce it to best of your ability.
3) Confirm that it still occurs on /luaui disable and /luarules disable
4) If it fails any of above tests, submit it to ZK bug tracker. You can probably start using the Github tracker
here since github migration is pretty close to completion (and issues made there will be reported into #zkdev immediately). Alternatively, you can use the
google code tracker at risk of noone ever seeing it, or use the forum section for help and bugs.
5) If it still happens with above disabled, it's probably an engine bug. Collect full information, including replay link, replication instructions, versions of engine and game used, infolog.txt, used settings, hardware specifications, OS version, etc.
6) Check all your data with extreme rigor, and if you feel like the developers will be able to understand and reproduce the issue, submit the issue to Spring engine
mantis.
Just writing "shit lags, it all lags, lags lags lags, shit shit" -- like most [troll] people do - is not just useless, but extremely counterproductive.
