Unable to upgrade from horse transport to truck.
'Not enough command points'

Can't repro so far in Steam 922. In editor tests can upgrade both UK 3,7in and 25pdr from horse to truck, buy anew, upgrade from none to horse, then to truck and so on.

Your pic - it this modded? Those TPs show a cost of 1 CP for me when buying.

I did encounter this "bug" from time to time (in the vanilla version) already.
It usually happens during the deployment stage after you have placed all your units on the map and have no CPs left and want to upgrade an unit's transport.
(Even if that new transport unit has the the same CP usage as the one before!)

The easy "workaround" is to undeploy some other unit, upgrade said unit's transport and then redeploy the undeployed unit again. If you understand what I mean. Don't get me wrong: In the end, the general CP count is not off, but this kind of "transport-upgrading" just don't work if you have no CPs left. That's all.

This is the standard Allied Defiant campaign.

GabeKnight is right, but it looks like the workaround is good only in the deployment mode, not in a later turn (?)

Yep. Maybe I shouldn't have put the word 'bug' inside quote signs. Because, yeah, it's a bug.
