Lmao it is easy. The reason why Crazyblox replaced EventScript to EventString is that there are some users who are abusing the EvntScript, EventString existsd so that there are limitations in the events that will happen in a map.
FEMAP Making Kit was updated. Go to Instructions. Check out the new lines below the script, it will guide you in EventString.
To code, copy the whole EventString code. Make a script, then paste it. Then, move all the last text (of a line) to the next line. (Like SetWaterState , wait(0) etc.)
