Using too many Tilesets at once causes a crash that prevents Tilesets/Vector Data from loading #841
Description
As you know, you can use multiple Tilesets together by specifying comma separated mapIDs in the Unity inteface.This allowed a Unity map to draw features from several different datasets.
However, when I got up to 4 datasets, this stopped working. The application would run, but no Vector features would get draw. I'd also get this error multiple times:

All Tilesets worked on their own, any combination of 3 Tilesets would work, but try all of them and this crash happened.
A clue why this is happening is that the filepath: "C:\Users\MT_User\AppData\LocalLow\DefaultCompany\Radial Menu Test\cache\pablofinquez.cjhuozqy617dv2vo2j0q5w82z-9arq6,pablofinquez.cjh0pxmyi0v8p33mqev5h6ire-4qfll,pablofinquez.cjhvqj3yh0xdi31n13ztkk8a0-6sndr,pablofinquez.cjhum69ji00cy32li8a4hn3jx-0dkip.cache" is 257 characters long. I recall something about problems with filepaths that are more than 255 characters long.
I any event, this project will likely involve more than 4 tilesets, so any suggestions on how to avoid this problem would be appreciated. I'd prefer not to have to squish everything down into a single Tileset for reasons I've outlined in #830 , though I'm sure it would work.
