"Spoilage" on production and tech progress?

[Havan_IronOak]

It's not entirely clear but if one changes what tech one is studying or what one is building in a city, is any of the progress accrued to that point lost over time?

[BatMart]

no

Sometimes I see production loss for units that you stopped building but I'm not certain what causes it. Buildings, wonders, and techs/civics always keep their progress though.

Just an FYI. In the old days of Civ II, the current production was halved when you changed to another wonder, but not when it came to units or buildings. I don't believe Civ VI awards any carryover construction credit.

Civ VI doesn't carry over hammers from project to project, but I think he meant when you get let's say 10 out of 20 hammers for a unit, and then switch to let's say an armory wanting said unit to have that extra XP boost when it finishes, will it still have only 10 hammers left to go upon completion.
From what I have seen yes, it will remain half done. The changing progress you others mentioned I have seen before but since realised it was because of extra 50% hammers toward military units Civic policy I would adapt, then get into next era and it no longer gives that bonus.
Maybe that's what you saw as well?

No, occasionally the progress of units that you halted just straight up disappears.

Did you tech out of those units? For example were you building an archer and the researched Machinery and unlocked crossbowmen?

I think so. It's definitely stupid behavior though considering you keep the progress if you were building the unit at the time.

That's strange, never noticed that but I try my best to stop producing a unit a tech or two ahead of when I unlock the new one. I would rather get a couple more later then pay gold for unit upgrades, kinda dumb seeing there are policies that reduce the cost but I perfer to stockpile gold for powerpalnts and stock buildings etc late game, since they are 1000 plus or a boat load of turns a piece, later game I can make 3 units in the time it takes to build that 1 building

Could be a change in production by the city. Maybe a citizen has changed priorities. Left a mine for food or whatever.

Again, I don't mean an increase in the time to make the unit. I mean that accumulated production disappears. The progress bar vanishes because the work you've done ceases to exist.

Nothing is lost. However, if you tech to a higher quality unit then the previous unit will be entirely removed (eg. if you tech Stirrups and had hammers in a Heavy Chariot those are gone and you start anew)

[BLACKcOPstRIPPa]

So unts are kind of a question still though I honestly have never noticed a decay of hammers.

Tech- I have never seen tech go down randomly either in progress. Only down I have ever seen is I research as far as I can to get the research when getting the eureaka moment for it but end up not meeting the requirments so 20 or 30 turns later I decide just to finish rest of research manually and thus now it has 4 turns left instead of 6 because of new science buildings and districts giving higher science output. This isn't a decay however.

Except you don't lose the progress if you were actively building the unit at the time, which means losing it otherwise is a dumb mechanic.
Plus I've seen a situation where I was building a unit when it got upgraded, then switched to something else, and all the progress was lost.

I agree with gimmethegepgun and I'd go further and say we should be able to select a "show obsolete" box and start from 0 the production of units from previous researches, the reason is strategic resources, you research swordsman for example and get screwed without any iron that you can get or buy and you are denied building basic infantry for a very long time until you settle near one or the AI gets two copies to sell one.

The above is valid for every strategic of every era, in my current game I can't make battleships because there is only one single coal in the entire continet, the ai wont sell it and there are 3 civs between them and me so I cant take it by force, but I can no longer build frigates either so I can't make an effective naval defense against the attacks being thrown at me.
