When a raid was finishes it still display "Raid - Mobs remaining: 1"

Cannot reproduce.

I did some looking into it, I had a similar issue (2 times) before, it seems it was due to raid mobs spawning in caves down below the area under the village, found them by going into spectator, and I do wish to note that both of the 2 times it happened, it was a witch that had spawned in the cave, but I am not sure if that is what will always happen, or if any of the raid mobs can have this issue.
Edit: I should add that both of two instances happened in 19w08, the first one in a and the second one in b

I did further testing, it seems that naturally spawned witches become part of the raid if they are close enough when it starts, and this can cause issues when a witch is in a cave below the village that the player is unable to access or does not know about, as the raid will seem to be stuck with 1-2 mobs remaining due to the witches in the caves, maybe this behavior either should not happen, or there should be some sort of check if a witch is visible to the sky before making them part of the raid?

This issue related to mobs naturally spawning being added to the raid party is now fixed in 19w13b.

Please check if that's still an issue for you in the latest 1.14 (pre-)release.

I have this issue on the PS4 version, have there been fixes for this in recent or upcoming updates? My current version is 1.92.

I too have this issue on the PS4 version (1.92) Are you planning on fixing this? It has been like this for months. Not acceptable.

Having this problem on PS4. Had a raid at my base and now it's stuck with "1 mob remaining" says it's resolved but clearly isn't... Please sort it out

:O Figured it out! Open the save file in peaceful, run quite a fair distance away from where the raid happened, exit and safe, open the file on a difficulty and go back to your base. Mine sorted itself out with that
