A new stealth bug

[tinkthank]

I think the phenomenon has been mentioned before, but not quite the circumstances.

The computer will remove or delete a friendly stealthy commander if this commander sneaks into a territory, has a battle, and loses. I believe but am not 100% sure yet that the province must be owned by independents.

I have tested this in three different scenarios now; it is not easy, because the bug has two phases:

1) The computer must have the stealthy commander engage the enemy after sneaking. Normally, this would prompt the "X has been discovered in Province Q" message. But this does not occur.
2) The stealthy commander must survive the battle and must attempt to retreat into a friendly neighboring province.

Upon successful retreat, the commander and any stealthy troops which also may have survived are completely deleted.

I tested this against 1 AI nations with stealthy commanders so I can easily get them into the hall of fame for better tracking. They are not reported as dead, just missing.

I tested this once with a pretender; the pretender also goes missing and is unrecallable by priests.
This could be a nasty bug if your pretender is stealthy.
