I've set up my server using this tutorial (https://github.com/rathena/rathena/wiki/Install-on-Centos), but a few problems appeared.
First, when my emulator was at commit 32c68c7, the mapserver would crash when a player feed the pet or homunculus.
Now, I updated to latest version (f5f377a), but some ground type skills (storm gust, vermillion, grand cross, sanctuary, severe rainstorm and several others) have a much greater duration, and some don't work at all (like meteor storm).
I suspect something on my machine is messing up the compilation, because I tested the same code on windows and it works.
Does anyone have any idea what I could test to solve the problem?
