Cells moving and capsules splitting

[Effece]

A fun thing to observe is that sometimes, two cells stay joined but split up.

My theory is that I forgot to change the coordinates of some of the cells.

I might have fixed it, there is a test ran to avoid removing a cell that fell in the same iteration that was incomplete. Basically when a vertical capsule falls, if the bottom cell falls after the top cell which should always happen, the one on top has already changed the value on the grid where the bottom cell used to be, so the bottom cell needs to not change that new value to 0. However the test only verified if the cells were fused and not if it was vertical.

I'm not sure this solves the issue so I'll keep it open until I'm almost certain it isn't linked to something else.

The original problem wasn't actually corrected after my first comment. In the last three weeks I am almost certain I have corrected those bugs, however new bugs identical to those have presented themselves with the "gift" and "elevator" events.

For information:

• I don't remember exactly how I solved the invisible cells problem, partly with the test I had explained earlier;
• for the capsules splitting, I added a parameter to force a capsule to fall even if it isn't detected as "fallable". The problem was that the test to check if a cell could fall was done when the fall function was called, which means most of the time one of the two cells had already fallen. I've temporarly fixed that by making an array that contains which cells can fall, then they fall, but having a copy of the grid could be better.
