After building a steam turbine and a wiremill, while preparing to craft a polarizer, I started getting crashes like this every 5-10 minutes:

Initially I thought it might be related to updating Forge, but rolling back to Forge build 2079 (as listed in GT 5.10's build.properties) didn't help.

Edit: also tried rolling back CodeChickenLib to build 178 (the closest build after 162 that build.properties lists that I could find on CurseForge), and it still crashed.

I took a stab at debugging this - codechicken.lib.render.BlockRenderer$BlockFace.loadCuboidFace looks like this:

        public BlockFace loadCuboidFace(Cuboid6 c, int side) {
            double x1 = c.min.x;
            double x2 = c.max.x;
            double y1 = c.min.y;
            double y2 = c.max.y;
            double z1 = c.min.z;
            double z2 = c.max.z;
       /* ... */
       }

line 53 is the assignment to x2, indicating that the Cuboid6 exists, but c.max is null (while c.min is non-null). I could only think of two ways that could happen:

  1. RenderBlocks.setBounds was called with an incomplete Cuboid6.
  2. The Cuboid6 passed to RenderBlocks.setBounds becomes incomplete sometime between that call and the call to RenderBlocks.renderFace (since it was stored as a reference, instead of copied as a new Cuboid6).

Thus, I tried changing RenderBlocks.setBounds to copy the values from the passed Cuboid6 into local variables, then creating a new Cuboid6 with them to set the static "bounds" variable with. If way 1 was correct, the game would now crash in setBounds instead of in renderFace, and I'd be able to track down why only the max vector was null); if way 2 was correct, the game would no longer crash this way at all. Instead, it crashed in the same place as before, leaving me very confused.

Adding a try-catch to squelch the NPE for the first line of RenderBlocks.renderFace (which isn't good practice, I know) seems to at least prevent this crash and make the mod technically playable for now.

Stop doing "i fixed it locally but i won't pull request".

Sorry, but

  1. Most of my local fixes so far are so small they're simple to explain without a pull request.
  2. I don't know GitHub well enough to import the new branches into my existing fork - if you can find me a good explanation for how to do that, I'd be happy to set up a pull request with some of the fixes I came up with.
  3. This particular local change is a hacky temporary workaround, rather than a fix, so it wouldn't belong in a pull request.

Edit: I thought of a slightly less-hacky way to deal with this bug (still not a true fix IMO), and I've deleted my repo and re-forked (which picked up the extra branches). I'll set up the pull request soon with at least my other fixes. If my new idea works, I'll include it as well.

😞
My new workaround wasn't as effective as I thought. I tested for a little over 20 minutes before setting up the pull request, but at around 50 minutes it crashed.
