-e: 4.3 seems to have an obscure problem with loading asset bundles that have scripts inside them. We get this error message:

AssetBundle loading failed because the UnityItemConfiguration script serialization hash does not match. Supported: dbb389f8, loading: 5e929c60

This basically breaks all nontrivial web player games.

-repro:
--clear your webplayer cache
--run uberstrike with the 4.3rc3 runtime
--try joining a game
--NOTICE you get an error message saying that it can't load the map you try to join
