Love the game with two to five, but everything can be improved upon, right? Well, this may or may not be an improvement, but I'll put it out here. One thing that bugged me is that I feel less control in two player because the the random bot roll. If there were a (rational) player there, I'd have some indication what he might be picking.

So here's my suggestion. I've worked the math on it, but haven't played it much.
Openly roll a home die ahead of time for the bot.
After the players have planned, roll four more home dice.
If there are three or four explore icons, the bot will explore.
If exactly one other icon shows up two or more times, change to that action.
If neither of the above are true stay with original roll.

This should result in staying with original roll ~50% of the time otherwise switching roles with roughly equal chance to one of the others (explore is slightly less likely).

This is based on following calculations for four home dice:
Three or more explores will happen ~11%. Pairs of the other icons will occur ~13% each. Two pair will happen ~2%.

The first post gives players a ~50/50 indication of the bot's role selection. This is lower than I'd like, but has the benefit of only using available dice.

If you prefer a greater (or lesser) chance of knowing what the bot is picking, you could add a d6 or d10 and roll it after player role selection assigning a keep probability. Say 1-7 on d10 is keep the initial roll while it's rerolled on 8-10. The reroll could either be one home die or use the four home dice scheme outlined above.

I've been thinking of trying to use the other coloured dice based on the last phase the boot rolled, ie. If it rolled an explore last turn it rolls a red / military dice to increase the chances of following with a develop/settle which to me would seem closer to a real person, though I've only played a few times so far.

I'd prefer there might be a way to veto what white dice can be rolled.

Maybe both players pick a phase and veto a phase, if the die rolled is a vetoed phase, it doesn't happen.

The idea behind this is sometimes somebody gains way too much from calling a certain stage so nobody should rationally ever call that actions. in a 2 player game, that player is helped out occasionally, when they should reasonably never be helped out.

Vetoing Explore is probaly too strong change.
Home dice are purposely "specialised" in Explore. And Explore veto would mean that 1/3 of times there will be no additional phase.
And Explore could can be rationally called by any player in any turn. Stocking is important economic move.
