Will this fix the mutable? The answer may surprise you!

[LovamKicsiGazsii]

Summary

None

Purpose of change

I don't know if this fixes #65983.

Describe the solution

The mutable was having some trouble when three tentacles wanted to end at the same spot. So I added a "tentacle tee" at the end of the generation line to hopefully fix that. I made the chances of it spawning rare enough to spawn only when it's absolutely necessary.

Describe alternatives you've considered

Fourway connections are not accounted for, but I imagine it is magnitudes rarer than the already mythical three-way connection so I'm not too worried.

Testing

Fast-scrolled through Overmap for ~5 minutes. No errors. Not that it means anything.

Additional context

None.

[RenechCDDA]

I'm running local tests (currently 8 passes....) on a similar implementation right now, I think you may need to change the connection rules for tentacle_tee as well to avoid errors when tees are adjacent to tees.

I used this:

      "tentacle_tee": {
        "overmap": "corpse_tentacle_nes",
        "north": { "id": "tentacle_to_tentacle", "alternatives": [ "tentacle_tee_to_tentacle" ] },
        "east": { "id": "tentacle_tee_to_tentacle", "alternatives": [ "tentacle_to_tentacle" ] },
        "south": { "id": "tentacle_tee_to_tentacle", "alternatives": [ "tentacle_to_tentacle" ] }
      },

Of course it failed right as I was typing this.

[RenechCDDA]

Failed locally on tests.

Output(with the same added debug messages for nearby terrain):

I'm running local tests (currently 8 passes....) on a similar implementation right now, I think you may need to change the connection rules for tentacle_tee as well to avoid errors when tees are adjacent to tees.

I used this:

      "tentacle_tee": {
        "overmap": "corpse_tentacle_nes",
        "north": { "id": "tentacle_to_tentacle", "alternatives": [ "tentacle_tee_to_tentacle" ] },
        "east": { "id": "tentacle_tee_to_tentacle", "alternatives": [ "tentacle_to_tentacle" ] },
        "south": { "id": "tentacle_tee_to_tentacle", "alternatives": [ "tentacle_to_tentacle" ] }
      },

Of course it failed right as I was typing this.

I decided to go one step further and deleted "tentacle_tee_to_tentacle" and its opposites altogether. I also tried testing the flexibility of the generation and bumped the tentacle tees to spawn 10000x as often. It worked without issues.

This passes the checks for now, so here's a hesitant yay! from me. God, mutables are such a headache!
