I looked up the id nr. of gold ore (#14) and baobab leaves (#552) but I can't figure out, why the one should be repaced by the other and what this has to do with 4096, but maybe I am just to dumb for it.

IDs from the mod are not static. Forge automatically assigns them and they can change depending on the mods you have loaded (That's also the reason why we don't have ID lists here on the wiki). Beside that, I can't imagine what happened myself. But code can behave weird sometimes...
