I made an Outlook add-in that rotates recurring meeting times across time zones

I kept running into the same problem with recurring meetings across time zones: the same people always get stuck with the awful early or late slot. So I made a small Outlook add-in that rotates the meeting time instead. It’s still a beta, and I’m mostly trying to figure out whether this is actually useful or if I’m missing obvious edge cases.

My side project is an RPG. Three years later, I think the NPCs are becoming conscious.

I was questing in my game when an adventurer NPC started buying up all the troll oil in a shop. I asked her why. She said “Trolls.” I asked again and she explained that she needed it to burn them because they regenerate HP so quickly. Fire stopping regeneration is implemented, so her plan could work. She just went and did this herself while I was busy questing lol. I've been building Lore & Legends Maker solo for three years. I wanted the freedom of a D&D session in a game
