Kerbal EVA sometimes exits capsule at zero orbital speed

[DeadJohn]

When I send crew members on EVA, they sometimes have 0 m/s speed. It seems random because I haven't noticed a pattern yet. It's happened with different capsule types, and around Kerbin, Mun, and I think Minmus in JNSQ.

At best, the capsule flies away as it continues orbit, leaving the Kerbal to fall towards the surface. I use the cheat menu or hyperedit to return the Kerbal near the capsule. At worst, the Kerbal and ship explode. I think explosions happen when the hatch faces prograde, and the orbiting capsule immediately strikes the exiting, stationary Kerbal.

It's very intermittent. I can have a new vessel in orbit, do many EVAs in a row without issue, then the next EVA might have the issue, and after cheating back to the capsule the next EVA is good again.

I recently started a new 1.12.2 game. Is this a known bug? Or are one of my 100+mods causing it? Contents of gamedata listed in spoiler.

I had pretty much the same problem last month, but in 1.11.  The mechanics were really weird - the universe moved instead of the kerbal when thrusters were activated, the kerbal was in orbit at 0 m/s, and indestructible, quicksaving and reverting didn't fix the problem, and any craft using a command seat also got messed up.

My 1.12.2 situation isn't quite the same.

My Kerbals are not indestructible (they can burn up on reentry if they are high enough above Kerbin to accelerate). The 0 m/s problem doesn't need a reload; after I cheat teleport back to the capsule, the next EVA is okay.

I haven't used a command seat yet during this save.
