Like Chris suggested, it sounds like you're not only adding some fields but also dropping some. SDT does the ADD COLUMN work first and DROP COLUMN work second for reasons documented in the SDTMgr.HowToSyncTable method. So, while the net result may be adding 20 fields, if you actually add 30 and remove 10, this will fail because the 30 added fields take you over the 254 field limit. Is that the case here?
