I tried this version http://www.sourceop.com/downloads/Source...op_i486.so but if you create a door it will crash a server (I made doors using my own plugin on eventscripts,it's just use Ent_fire command with sv_cheats 0)
In version 0.9.0 ( http://www.sourceop.com/modules.php?.9.0 http://www.sourceop.com/modules.php? ) I can create working doors .

I can't really help unless you post a stack trace from the core dump. When the server crashes, it should make a new core file in the same folder as srcds_run. Do:
gdb ./srcds_i486 <name>
And then when gdb loads, type bt and copy and paste the output here.

And size of 0.9.0 is much bigger than version of plugin in this thread I think it means something

No.

Another problem is then somebody gets in airboat it makes all players look in specific point (it sets they angle)

This is a bug in the game, not any plugin. The airboat was only meant for single player.

Soory, my hosting doesn't allow me to view this files (folder). But know, that version of SourceOP from downloads works pretty good and doesn't have this bug with doors.

Can you just add cvar DF_spawn_removeondisconnect in this version?

It will really helps me.

Now I have to create own autobuild plugin for every building to save it or create it very fast (few seconds).

But autobuild can works faster if I will use e_spawnprop and +copyent command.

But entitys spawned with e_spawnprop or +copyent then you disconnect.

That's exactly what this is:

I don't know why spawning doors is suddenly crashing for you. Perhaps post what commands you are using and when it crashes and I will see if I can reproduce the problem.
