Last night myself and a group of friends were testing my map on our server for the first time. As soon as the map started we were getting several bugs which none of us could explain. In fact it is so hard to explain that it was hard to search these forums for similar occurrences so my apologies if there is a post/guide about this somewhere already. The best I can do is provide a list of the main symptom that we saw happen. Rockets moved very slowly in the air and failed to detonate when hitting anything solid. Here's an example screenshot Trigger_multiples did not work at all trigger_hurts did not work at all func_nobuilds did not work at all Some func_buttons did not work, or were very slow in responding. The confusing thing is the map runs fine on listen servers. We even tried unloading all the plugins we were using and running the server completely vanilla but that did little. In fact it allowed trigger_multiples to work much like the buttons - only some of them and after a delay. I've never come across this kind of thing happening before. I've seen brush entities fail because of a mapping error but I've never seen entire types of entities fail and nothing on this scale. I would be most grateful if anyone could shed some light on this, its utterly game breaking and I have no idea why it happens.
