• #2518 Fixed enemy placement to match MDT.
• #2486 City of Threads map tiles redone.

MDT Importer changes:

• #2501 Created a new system to view and manage failed MDT imports (rather than me getting a ping every time).

MDT Importer changes:

• #2511 Imported routes from MDT no longer have their titles slugged (meaning, converted like: this-is-my-route-name).

Mapping changes:

• #2505 City of Threads: Eye of the Queen now has the correct NPC ID (the one that gives 20 count for each).

SimulationCraft changes:

• #2502 Fixed an issue preventing the feature from working at all. Added support for Tyrannical and Fortified at the same time. Fixed health calculation of enemies. Key level now scaled to the season's key level range.

General changes:

• #2495 Various performance optimizations. This is still ongoing.

Bugfixes:

• #2493 Route season filter no longer just looks for any routes that are for a dungeon part of the current season, but for actual routes created during the selected season. BFA routes for Siege of Boralus, for example, will no longer show up with this filter.
• #2494 Dungeons that have support for combined floors now show a thumbnail again.

General changes:

• #2467 TWW affixes now fully supported.
