Thanks for your longtime support and the bug reports!
Spam-placing items on vehicles: you raise a good point about it being abusable to easily get a bed into the sky. My guess is that something isn’t reset between frames so a well-timed click allows it to be placed.
Exploit: feel free to email me nelson@smartlydressedgames.com.
Stuck shooting in dead jet: thanks for the video. I will get this fixed for the next patch.
Getting stuck on ledges: annoyingly Unity’s built-in character movement will sometimes decide to go through things, e.g. it was consistently repeatable through the military tent interiors. To prevent this the server checks to make sure your character didn’t go through anything, but sometimes there are false positives like on ledges. The best long-term solution is to replace the built-in movement with something custom for Unturned.
Hotbar attachments: thanks for the video. Will fix for the next patch.
Fire boss attenuation: thanks for the video. Will fix for the next patch.
Hole in the plane: probably same as getting stuck on ledges.
Arrow durability: this one is intentional because arrows and silencers are “balanced” around their durability.
Tree explosive damage: most of the weapons have different damage values for trees and players. Explosive damage falloff is calculated from the pivot point, so trees take a lot more damage from the stump. This should probably be updated, but I am not sure when yet.
Nailgun ammo: will fix.
Planes using battery when idle: will double-check.
Repair fences and barbed wire: off the top of my head it can be finicky because players can shoot through them, but the fences should be repairable on their poles at least.
Tree models: yeah… I have been thinking about simply removing the speedtrees for a while now. The inconsistencies and performance are not worth it
Green skin: made somewhat worse by the fact each map has different terrain colors, so it’s not like a single color can be disabled. Unturned II will only have yellow and real skin colors.
Scope sway: eventually I would like to fully mirror the movement in the scope overlay. This is one of the reasons Unturned II will not have dual-render scopes. https://github.com/SmartlyDressedGames/Unturned-3.x-Community/issues/1122
Foliage: the rendering performance for GPUs without instancing support is really bad. Maybe in a few years.
