(I copied this from a post I made in the UK forums)
(At the risk of repeating http://forum.uk.bigb...e-conventions/)
All of the other Temples reward diligence, effort, a bit of skill.
Temples for Convention missions reward luck and stupidity. You have to be lucky to be on, and stupid enough to spend diamonds on the lowest return for investment in the game.
And the solution is VERY simple: Run enough conventions, all in Telleville, that this temple will indeed reward diligence and effort. We know you have the technology, you did it for Gay Pride week.
So my suggestion is this: either fix this temple to be more in line with all the other temples
Or stop using this miserable idea, and never repeat a Temple for conventions mission. Ever again.
Best regards,

I will certainly pass these along for you. Thank you.
