[14.21] Deconstruction markers time out, issue for placing BP

[Kenira]

After about an hour of placing a blueprint, deconstruction markers for trees / stones disappear and you have to either remove the things yourself or renew the blueprint to renew the deconstruction markers to allow bots to finish constructing.

Tested with no mods except TimeTools to speed things up.

That's by design. They're meant to time out as if a robot hasn't gotten around to it at that point it's wasting the robots time since they will probably never get around to it.

I did find it to be a problem when placing huge blueprints, like for solar arrays where bots also have to first get to place the roboports to be able to place further out items etc so more robots is not a solution (i am using plenty). Especially when the solar farm is already big so bots also take a long time to go between the items and the destination.
Incidentally this then also causes robots to waste their time because the ones trying to place an item are waiting there with the item in hand and are stuck.

try working on smaller sections at a time.

It's pretty annoying and takes time to have to come back to it all the time instead of just placing a ton of blueprints at once. I don't see why you can't increase the time until deconstruction markers time out so that it's not a problem any more, if it cancels after 1 or 3 hours won't make much of a difference for the rare cases it will actually never happen but it can happen relatively easily for constructions to take 1 hour.

If they never get around to it, how has it wasted any robots time?

Because it still has to be checked from time to time to see if any roboport is now in range. Player roboports move around as well as the car/train variants in mods.

That's a waste of player cpu, not robot time. Robots won't get any less work done in the same amount of ticks, ergo they aren't wasting any of their time.

That's by design.

When finite deconstruction order disappears from a tree/rock that blocks infinite construction order, robots are stuck flying over the ghost.
It clearly violates player expectation at least.
