Hello people i have found out that sponge not working whit flans because i have an recipe error

If you can give us a longer log file (or the debug.log file) it might help more. That one seems very short.
There appears to be a mixin conflict. Have you tried prefixing the spongeforge filename with aaa to force it to start first in the queue? That sometimes helps resolve mixin problems.
Have you tried using the recommended builds of Spongeforge (3361) and Forge (2705)?
