for the time being
**** leaked ****
Entity light_spot (12.67 1014.00 491.89) leaked!
thats the part you need to fix
load the pointfile after you have compiled - (dont even bother to run the game)
then you can use
view>go to co-ordinates to see exactly whats causing the leak - in this case it could be that the prop is outside the void - or part of it, or simply the poinfile will be going from the entity and out through a hole into the void, fix whatever that is, ignore the rest for now - re-compile and check for the next leak
its a good idea to use the vis-groups to swtich off things like func_details etc if u have any , that will help you visually spot any gaps into the void
