Known Bugs
This page lists all known bugs in the current stable release (28.0.6).
Bugs that are unlikely to be fixed
- MapWriter can stop saving map data correctly (and in some cases when this happens the map flickers). This also causes a massive memory leak which can only be cleaned up by exiting back to the main menu. Currently unknown what causes this - investigations proved inconclusive. (The issue can be made less frequent by increasing the RAM allocation to the game, but this has the side effect of causing longer, more laggy garbage collection stalls.)
- The IC2 energy net can sometimes trigger an infinite chunk load-unload loop on the server (chunk A unloading causes chunk B to load, chunk B unloading causes chunk A to load, ad infinitum). This tends to be triggered when teleporting away from an area with a lot of electrical machines and wiring. This issue was partially mitigated in more recent releases, and is no longer considered to be a major issue, but it can still be triggered in some situations; every situation which can trigger this has to be patched to prevent it and not all were caught. If you encounter this issue, and you're playing a single-player game where you have all your machines next to each other, you can try chunk-loading your base to prevent it from unloading when teleporting away. Bug reports which can reproduce this issue are appreciated, as this allows more of these situations to be patched out; it is however considered unlikely that every situation will eventually be caught and fixed.
- World generation can be extremely laggy and/or time out in some situations which are algorithmically taxing (e.g. in the nether, or in very tall forest biomes). This happens because world generation is single-threaded and runs on the main server thread, so the server can't execute the game tick while it runs the world generator. On the live public server, the lag was mostly avoided by pre-generating most terrain near to the spawn; in single player games this isn't possible so you might end up with heavy lag if you do a lot of exploring (especially in the nether, where generation can often time out).
- Links to some web pages don't work as those web pages no longer exist (e.g. the wiki). Due to how few people now use the mod pack, it's unlikely those web pages will ever come back, so the links will just remain dead. Redesigning the GUI layout to remove them was deemed not worth the time being invested.
- Some long title screen splashes can be hard to read.
- ChunkRemapper can't tell the difference between unmodded save versions from MC releases earlier than 1.9, so it claims it can remap saves from 1.8 and some snapshot versions of 1.9, but since these are newer than 1.7.10 it doesn't correctly do this.
- ChunkRemapper can't remap data from versions earlier than 25.2. To work around this, use 25.2 to remap these saves first. You can then remap the saves a second time from 25.2 to the latest release.
- Any outstanding issues with Minecraft 1.7.10 which don't originate from modding (e.g. lighting bugs); fixing these is generally considered to be impractical.
Minor bugs that may be fixed in future
- Sometimes discharged batteries don't stack properly.
