23:32 MTDiscord <herowl> I was trying to tell that it is weird, cursed and indeterministic. Notice how in the first video switching to a slot with no light, which activated a much weaker light fallback from offhand, was triggering the hampered block loading, and the torch aka the stronger light (which requested a larger area VManip) didn't, the light from it was visible when I was approaching the ground, so it did work, and there was no light from the other
23:32 MTDiscord thing when switching to it, and switching back and forth did hamper chunk loading and "unlock" it. The second video when the item from offhand (and therefore the fallback) was removed shows that there is no problem with block loading with either the light or no light in hand. I am claiming it is a proof that it is some weird engine bug, perhaps related with some synchronization code, because it's unexplainable otherwise. On our side, there is no
23:32 MTDiscord difference between main hand and offhand (larger is always chosen), and there is no difference between weaker and stronger light (aside of the size of the requested VoxelManip and how far it is spread using BFS). I am trying to get you or someone else with good general knowledge of the Luanti codebase to try to test it.
