[NTG-context] Wrong cache-path with luatex

Hi! Within my luatex-chache directory there is the directory "2afa1e18082b2d9b8e2af9f2c6e925a6". But when I call texexec --lua it searches for a directory called "0aa031a3f94c398f99a9660a610ae9ef". I linked this with the existing one, but now luatex can't find any fontfiles anymore. Running luatex with --fmt=.../2afa1e18082b2d9b8e2af9f2c6e925a6 everything works fine. luatools --generate says alot about 2afa1e18082b2d9b8e2af9f2c6e925a6. I'm using the latest Contextgarden-Beta. Any ideas how to solve this? Best regards, Eyke
