Yeah, I&#039;ve noticed some other differences between single player and multiplayer, for instance on map01 you can only rjump up to the side on I believe red&#039;s base, but not blue&#039;s, but online you can&#039;t rjump on either side. <br /><br />I had some problems myself on my map where I couldn&#039;t rjump in a base. Not that it&#039;s needed, but no splash damage on a ground anywhere isn&#039;t good in my mind, so I seemingly fixed that by changing the way the nodes were built, a tip I picked up on IRC one day.<br /><br />[i]To change the way nodes are built, go to:[/i]<br /><br />[B][u]Tools -&gt; Game Configurations -&gt; Nodebuilder Tab[/u][/b] <br /><br />and try changing them to something else. I believe the default is ZDBSP or ZenNode, and I believe I changed mine to glBSP which fixed the splash problem.<br /><br />I mention this because the lava might have something to do with that, and it&#039;s something for all authors here to consider checking.
