[Resolved 0.2.10] Why does't Iron+Copper ore smelt anymore?

[Slythercon]

I have just installed the new update (0.2.9) and when I went into my game the ores won't smelt, any help?

[syneris]

It seems 0.2.9 broke smelting on previous saves. You can try to go back to 0.2.8 or start a new map.

Have done, thanks for help.

Could you please send me the save?
I did some fixes, but I didn't have problem with iron/copper not smelting.
We definitely aim for backwards compatibility, but all of my old saves are working correctly now.

Sorry, I would have sent you the save but I've already gone back to 0.2.8

[kovarex]

Thank you for the report and save, is fixed for the 0.2.10

Have same problem with steel bars. in 0.2.9 my factory from 0.2.8 save reject to smelt steel plates to steel bars. I resaved this game in 0.2.9 after I came back to 0.2.8 but it looks like Factorio saves has't Forward Compatibility. Now I'm getting error when I'm trying to load game save from 0.2.9 in 0.2.8.

You got the terms wrong.
This one would be "forward compatibility"

In 0.2.10 your saves from 0.2.8 and 0.2.9 will work (Nothing is 100% but I tested it and everything seems to be ok now)
