[2.0.72] Positional Pins from deleted surfaces remain in save file

[Miiohau]

What happened?
Positional Pins remained after I removed Planet Pelagos (https://mods.factorio.com/mod/pelagos) and showed up on Arcanyx (https://mods.factorio.com/mod/Arcanyx)
what I did to reproduce it:
1. created a clean save with only Pelagos and it dependencies.
2. went to Pelagos and created positional pins (by option clicking on the map where there was no tag), a pin with an associated map tag (by option clicking on the map tag) and a map tag without a pin
3. left Pelagos so it could be removed as clean as possible. (factorio-current-pre.log and left_over_pins_pre.zip are from this point)
4. swapped Pelagos and it dependencies for Arcanyx and it dependencies.
5. went to my space platform and noted the Positional Pins were still there but no remote view was available for them. (made left_over_pins_mid.zip here)
6. landed on Arcanyx. The Positional Pins now have remote views and are visible on Arcanyx's map. (left_over_pins_post.zip and factorio-current-post.log are from this point)
What did you expect to happen instead:
for the Positional Pins to disappear or pins with an associated map tag to act the same as those with only a position.

Thanks for the report however this is working as intended. The pins stay until you remove them.
