In yesterday's meeting between Ognjeni Mač and Krvomeđe, it was decided that Crolarp 2014 is not going to happen. The official reason is "due to current circumstances in Croatian larp".
The more detailed reason is probably Ognjeni Mač switching to the new ruleset and world that is going on now, which (in combination with falling out of some organizers in 2013 and some scheduling issues) made the current model that Crolarp is using unfeasible.
So, Crolarp is on ice at the moment. In the meantime, you can read the available reviews of events in 2012 and 2013 - the two years when Crolarp happened. Will it get restarted in the future, using the same model or a different one? Only time will tell.
