As an aside, I changed one bass up a gauge with the same strings and there were no problems whatsoever, but the bass with the problems I changed but to the same gauge. Why would the first bass accommodate a gauge higher quite happily and the second bass wouldn't accept the same gauge? One a Squier VMPJ and Two, the problem bass, a Jim Deacon P copy (don't mock me, it was a freebie!)

This is a guess but ... perhaps the Squier VM, which is a very good bass for the money, is simply more stable such that a small change in gauge of same make/model of string, so small change in tension, leaves you with a bass that is still functional even if it might still benefit from a setup.
Meanwhile, the Deacon, which I know nothing about except that they are cheap even compared to the Squier, being less stable in its neck wood and truss rod, is going to suffer greatly from a change of make/model and gauge of string and will definitely need a full setup to be playable.
