[Rseding91] [16.17] Tile limit reached, 16.16 worked

[Opiboble]

So I just updated to 0.16.17 and I can no longer load my map:/ wasn't that long into it so not the end of the world... can start up new map no problem. So don't know what is up.

The game can only allow for 255 tile types; did 0.16.17 add any new vanilla ones? Did you update any tile-adding mods?

There was a note in scripts about tiles, but wouldn't that also prevent me from creating a new map? I can create a new map just fine, just not spin up my current one...

Perhaps a tile changed names, and before the old one is cleared the new one is declared?

Still a problem in 0.16.18... Is there a location of a log that I can look at to see what is using up all the Tile limit?

There was one tile added by vanilla, so you probably use some mods that use a lot of times and you ran out of the ids.

What is the likelihood (read: difficulty) of getting the tile limit increased by a byte making it 4095 max?

I got a number of saves I can't load directly anymore because of this error.

Have to disable just the right mod, load, save, reenable the mod and it seems to work just fine until the error randomly reappears again on loading.

Increasing the tile limit by a byte isn't going to happen. It would increase the memory footprint of every chunk by 32*32 bytes and with saves having between 1 and 3 million on average that's a massive increase in RAM for something that goes completely unused in the base game.

What I'm thinking I'll do to address this is change how tile migrations work so if the game runs into a situation like this where it literally can't do migration logic correctly because it runs out of tile IDs to load the save file it will force migrate previous tiles to make the game loadable.

It will let you load the save(s) but it's going to migrate tiles (at random from a user perspective) to different types and result in very broken terrain.

@Rseding91

I can understand you don't want to raise the amount of IDs, memory usage for every tile and so on.
As a Programmer I faced similar problems, a byte can be very much if you save it several million times...

But:
Would it be possible to run migrations before the too-much-tiles-check?

Or have a "Proceed anyway (CATION! May ruin Map)"-Button, which would remove all tiles > 255 and set them to grass-1.
This would at least let you start the game (to remove mods) or transfer most of a save.


ATM i can't migrate an 0.15 save with Alien Biomes + Angels+Bobs (but no Asphalt or something like that) to 0.16 with Alien Biomes + Angels+Bobs.
Overall there may be 170 Tiles finally, but during first load/migration it's well over 255 because all new and all old tiles seem to exist simultaneous till migrations are run.

Ok, this is now fixed for the next version of 0.16.
