Have this new patch fixed everything for real? So if I play New Vegas right now, will I find Dennis Crocker after being idolized by the Boomers?

Everything? No, not by a long shot. Mostly the glitches that the patches have fixed are things like game freezes, super long load times, getting stuck in VATS, getting stuck on landscape, and similar. I don't know of any quest type glitches that the patches
have fixed. You can always check though, you never know. Also note that the specific bug you are talking about doesn't always happen, I was able to find the Ambassador despite already being idolized by the Boomers. So I'm thinking that it may actually be
related to having completed some specific Boomers related quest like Volare. I imagine most people probably run off and complete that quest as soon as they get it, but I took my time about it, and may have found and talked to Crocker before finishing it.
