I wanted to use the Supplier Pipe to transfer oak saplings to (1) an MFR Planter and (2) to a normal Minecraft chest. In both cases I got a java.lang.IllegalArgumentException and a ticking block entity (the Supplier pipe) and my game crashed. The game just produced the error when I put a sapling in the Supplier Pipe configuraion. I used the FTB Infinity Modpack.

Please for the love of readability put that in a ghist or a pastebin and link to it.

Cant reproduce this error. You might have catched a bad download of the Pack wich corrupted LP. Have you tried redownloading?

For safety: use this download page for get the right package. All other sites (except maybe Curse and CurseForge) are subject to contain wrong or corrupted version.

No answer to track down the bug.
