Review all ground-based (at least) scenes to check for any blank spots, D12 in particular for layering issues.

D11, 12, 13 edge cases where tiles can be hidden fixed

Manananggal healing no longer adjusts its invulnerability to 1 (an edge case because I forgot, at the time, to explicitly allow only the PC's post-hit invul to 1 after healing. A latent issue)

Fixed some issues where going to certain crisis trigger or dodge tool stages and then returning to the room where you select on still leaves you in trial mode (limiting your equipment temporarily and giving you a seperate, trial-specific score value.)

Added an extra air checkpoint to 2-A (non-poisoned timeline) after the Quetzalcoatl passes through and escapes for the first time, if it lives that long.

Added 4-B air and ground, including several EX bosses (and the Gravity Generator), which took some time to do.

Added 4-C air boss (Beacon Guardian) and completed air boss rush (with the guardian at the end.)

Sometimes when you died after facing Koschei, the game crashed. I put a conditional to check whether the PC is alive before tracking Koschei behaviour in response. Also, the Sulfurous Blast technique it has did damage on its tell due to me not setting a conditional on the ability that only allowed damage on the flame or the scorch mark. The conditional has been added now.

Cybele occasionally survived at 0 hp if there was another insect on the screen. No more.

Seraphine is invulnerable for 1 second upon entering a zone.
