1:09:50Q: You mentioned yesterday about choosing between two ways to solve the problem of large entities that overlap the sim region but are not in the selected chunks. It looked to me like you could use both solutions. If the entity is larger than the max entity size, still allow it and use the add it twice approach. Would this get you all the advantages of both with neither of the disadvantages?

1:12:42Q: Yesterday you mentioned that when jumping up to a chunk above, the character would jump over the ground level Z=0 and then come down, however, since the jump code is making the Z position go to 0 from negative, wouldn't the character be pushed up to 0 as soon as it reached the low side of the upper chunk, and won't this cause problems when trying to move the character up the stairs?
