I'm still using the 2012 version and something strange is going on with temperature settings. I definitely have TEMPERATURE: YES in my d_init file and it's clicked YES in the launcher, but when I use certain tilesets especially my favorite Phoebus, the game no longer does temperature changes. I know that the tileset change resets the launcher options, but I'm positive that I have Temperature turned on. I even checked the d_init file when the game is running. Other tilesets definitely still work. I'm running Mavericks if that matters at all.
You found some weird shit. Congratulations.
I can confirm that it's happening, but result are inconsistent and couldn't nail the problem down. I was able to reproduce this on 10.9.3 and 10.7.5 too, but only with Phoebus, none of the graphic packs exhibited this behavior. Then I managed to get temp. calculations going by deleting twbt and mousequery plugins, but I don't know which one may be the culprit, as the save fixed itself after: when I copied back the same version of both of these plugins the bug vanished, even though I did not modify the save game.
Weird...
So my best bet for now is to delete the twbt.plug.so from the hack/plugins folder, and check if this solves the problem. If it does, try moving it back, and tell me what happens. As far as I know twbt
shouldn't affect the temp. calculations, and then again if it did, it still
shouldn't bork only Phoebus.
