My Minecraft Forge 1.12.2 keeps crashing when I load it up with the Pixelmon Reforged version 8.0.2.  This is my first time working with mods, so I don't really know how exactly this works, but I have the crash report, if that helps.

1.12 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

      updateShape functionality deep dive

      By Sandermall · Posted

      Hello all. I'm currently grappling with the updateShape method in a custom class extending Block.  My code currently looks like this: The conditionals in CheckState are there to switch blockstate properties, which is working fine, as it functions correctly every time in getStateForPlacement.  The problem I'm running into is that when I update a state, the blocks seem to call CheckState with the position of the block which was changed updated last.  If I build a wall I can see the same change propagate across. My question thus is this: is updateShape sending its return to the neighbouring block?  Is each block not independently executing the updateShape method, thus inserting its own current position?  The first statement appears to be true, and the second false (each block is not independently executing the method). I have tried to fix this by saving the block's own position to a variable myPos at inception, and then feeding this in as CheckState(myPos) but this causes a worse outcome, where all blocks take the update of the first modified block, rather than just their neighbour.  This raises more questions than it answers, obviously: how is a different instance's variable propagating here?  I also tried changing it so that CheckState did not take a BlockPos, but had myPos built into the body - same problem. I have previously looked at neighbourUpdate and onNeighbourUpdate, but could not find a way to get this to work at all.  One post on here about updatePostPlacement and other methods has proven itself long superceded.  All other sources on the net seem to be out of date. Many thanks in advance for any help you might offer me, it's been several days now of trying to get this work and several weeks of generally trying to get round this roadblock.  - Sandermall

      crash dump

      By djdoyle1556 · Posted

      sorry, I might be stupid, but how do I open it? because the only options I have are too X out, copy it, which doesn't work and send crash report, which doesn't show it to me, also, sorry for taking so long.

      BUG: Cactus Flower Placement is BROKEN

      By Choonster · Posted

      Can you reproduce this with version 55.0.21? A whole lot of plant placement issues were just fixed in this PR.

      java.lang.IllegalStateException: Pose stack not empty

      By KenshinSpirit · Posted

      Necro'ing that thread to ask if you found a solution ? I'm encountering the same crash on loading the world. I created the world in Creative to test my MP, went into survival to test combat, died, crashed on respawn and since then crash on loading the world. Deactivating Oculus isn't fixing it either, and I don't have Optifine (Twilight forest is incompatible)
