I have been burned on the last two lighting system rewrites where my issues were ignored during the beta so did not bother getting frustrated with the beta this time. Let's see how this one went.
Copied a weekly game to Jumpgate today (8 January 2025). Things are a bit faster. Turn order markers from CombatTracker sometimes appear above the tokens so I can't select the token. Well, I knew about that. Okay, *deep breath*, let's try out Dynamic Lighting.
Wait, what? The token went through the wall.

Ah, walls are just suggestions now. Sometimes the token goes through the wall. Sometimes it doesn't. Does changing the wall thickness change anything? Nope.

Maybe it doesn't work in the non-Jumpgate game? Nope, that one is fine.

Hmm, it seems to have fewer problems with diagonal lines. Oh, wait. Now the entire map is registered as explored, including areas past the wall on the opposite side of the room.

Jumpgate: Smoother, Faster, Simpler, Cutting Corners
The current non-jumpgate lighting system was faster than its predecessor as well, until all the bugs were fixed and corners weren't cut anymore.
A Roll20 system declared ready for production which breaks after 2 minutes of simple user testing? Good to know some things don't change.
Don't forget the walls.

Wall:
Thus have I, Wall, my part discharged so;
And, being done, thus Wall away doth go.
