No textures for steam and related items.

No screenshot, no evidence.

A few other "missing texture for steam" cases have happened before as well; most of the time, it is caused by some other mods loaded before Railcraft adding broken steam. You should have filled out the issue template, at least the log part so that I can know what mods you have, etc.

Steam works and does have texture.

Sorry for long response this image is from beta-4

@chrizfilmz Give me your mod list (press F3+C for 8 seconds or more and upload the crash report). One of the mods loaded before Railcraft is adding steam.
