Summary0000095: [ 98d-alpha - Build 2980] Projectiles getting stuck/not dying in sky/other weird effects?
DescriptionNote this happens in the previous alpha build too. Only happens online.

It's a hard one to explain but I'll try my best. Basically we've been noticing projectiles getting stuck in random places, usually where there's a sky involved. From what I gather, it mostly happens with projectiles made by A_SpawnItemEx but can happen with A_FireCustomMissile too.
Steps To ReproduceAttached is an example wad that replaces the plasma rifle. Firing it spreads a bunch of new plasma projectiles that use ThrustThingZ to make them fly upward (A_FireCustomMissile). Altfire fires regular plasma balls using A_SpawnItemEx.

The easiest place to try out A_SpawnItemEx bug is on D2DM1. Go to the wall where the sky is (doomsphere secret) and use altfire towards the sky. The projectiles will remain IN the sky and sometimes not even reach the sky at all.

Another quirk with this is firing off certain ledges. Head to D2DM2 and no clip out of the map onto the ledges past the water. Now altfire towards the main building from the ledge. The projectiles get caught on the ledge, and won't go away until they hit the wall, but they're invisible to the client until that happens. Hard to explain but you'll see what I mean if you see it for yourself.

As for the primary fire, this a hard one to do but just spam it all over the place. I managed to do it a few times in D2DM9 at the window showing the sky. Spam plasma all over it and you should see them get stuck.
Additional InformationNoticed on MM8BDM.

It seems to happen for projectiles with irregular movement, or are spawned via A_SpawnItemEx.
TagsNo tags attached.

I forgot to mention, the projectiles don't harm the player or anything when they are stuck BUT they do exist and if there's enough of them it can cause FPS drops.

According to the feedback at 0000117 this seems to be fixed. Since this is a duplicate anyway, I'll mark this report as resolved, but leave 0000117 open till this is tested more thoroughly.
