But, I'm also not sure why you're having issues submitting deadlines, because that isn't an issue for me... on pool.burst-team.us right now...
Here is the current block, mind you I switched to ninja last night because deadlines sometimes were never confirming then the next block was starting so this is not an exact representation. Most of the deadlines on burst pool were starting to confirm under the FINISH block line sometimes up to 20+ secs after scanning all my drives. See how much later it took the 54933 deadline to confirm from the sending part. When I get home tonight from work I'll switch back to burst pool and show what it does.
