[Rseding91] [0.16.7] Recharging robots freeze if their force is changed

[Dustine]

Essentially, if you do (cell being a logistic cell):

Code: Select all

for _, bot in pairs(cell.to_charge_robots) do
  bot.force = "neutral"
  bot.force = "player"
end

any robots caught by this code that aren't near a roboport will freeze in mid-air, and nothing save from mining them seems to fix it (replacing roboports, forcing to swap the force of a robot once again, ...).



It's... really hard to replicate, as the bug only happens to robots within that array and not any other way I've tried so far, so I had to use a dummy mod (zzzDebug) with the code above on on_tick for it, which I attached to this post, together with two savegames where the bug is happening (with robots already frozen and some about to freeze the next tick).

Is there anything for them to charge at on the neutral force?

Is there anything for them to charge at on the neutral force?

Not on the examples above. I swear I remembered testing that yesterday, but just in case...




I tested it right now, on 0.16.11, on a brand new map with a neutral roboport nearby and they still froze in place. I attached the savegame with the neutral roboport to this post.
Just for fun, after saving, I set the game.speed to 100 and waited a bit, and they never recovered even after what the savegame timer said 20 or so in-game minutes had passed.

Ok, I found the issue and it's now fixed for the next version of 0.16.
