docking port seats eats kerbals

[StormCircuit]

eats as in makes them not appear in the vehicle whatsoever but they are at the complex and stated as still being inside the vehicle.

repro:

1. move kerbal to docking port seat (this step might be interchanged with step 2 as I do not recall precisely)
2. eva a kerbal
3. board the kerbal
4. kerbal in docking seat should be gone from the vehicle

[StormCircuit]

github bugged out and wouldnt attach the log to the original post
KSP.log

[StormCircuit]

EVAing and entering another kerbal fixes the bug. Reloading the scene (from the tracking station for example) did nothing.

Couldn't repro given the steps above. Interesting stuff in logs:

OK, got a solid repro:

vessel:
mk2 cockpit
mk2 crew cabin
mk2 docking port

3 kerbals - 2 in cockpit, 1 in crew cabin

1. take one of the kerbals from the cockpit and move to docking port
2. take the kerbal from the crew cabin and move to the cockpit
3. EVA the kerbal from the docking port
4. reboard the docking port
5. enter the seat in the docking port (note: if you don't do this the bug does not occur)
6. F5/F9

The crew cabin ends up with 2 crew members, but their seat indices seem to be set to the same number so only one of them spawns. Step 5 seems to be critical in changing the seat index; otherwise they would have been correctly placed in the crew cabin. The crew cabin might be an extra step; I wonder if you can do this with just the cockpit and docking port...

[JonnyOThan]

OK, simpler repro:

Vessel:
mk2 cockpit
mk2 docking port

2 kerbals - both in cockpit

1. EVA the 2nd kerbal from the cockpit (they are seat index 1)
2. Board the docking port
3. Enter the seat
4. F5/F9

[JonnyOThan]

OK even simpler repro:

Vessel:
mk2 cockpit
mk2 docking port

2 kerbals - both in cockpit

1. Have the 2nd kerbal move to the docking port seat
2. F5/F9
