Hi Indygoof,
Are you still around? It seems to me the toolkit has a bug on the skill use with replication. It always creates two fireballs for example, but the one on the server does not get lifetime set, so the server fireballs live forever and add up. I just created a new scene then set teh lifetime to just 5 seconds so it shows earlier, the fired one ball, waited five seconds, then fired the next, after one of the two previous vanished.
Kind regards
Tom
