Uploaded 2015-01-07_COC Bot v5.3.5.zip on the first post.
Reverted back to 5.3.4 by removing all of the 5.4 functions for the time being until sort out the whole memory leak issue.
Also changed some of the timings. Such as collect() will happen after 5 trainings to avoid collecting for no reason. Next release will include the stop/start as a workaround for the hang issue.
