[2.0.76] Fluid box energy source makes boiler non flippable

[Puke]

Hello,

This seems related to this : viewtopic.php?p=684822).

Setting the field "energy_source" of the base game's heat-exchanger entity like this :

Code: Select all

{
  type = "fluid",
  fluid_usage_per_tick = 100,
  fluid_box = {
    filter = "steam",
    volume = 1,
    pipe_connections = {
      {
        flow_direction = "input",
         direction = defines.direction.south,
          position = {0, 0.5},
           connection_type = "normal",

      }
    }
  }
}

Makes it non mirrorable.

For context, this new fluidbox's pipe connection is placed at the exact opposite of the "normal output" of the heat exchanger.



I tried the same thing on a square shaped boiler. It was STILL possible to rotate it, but again, not mirror it.
So rotation is possible, but not "flip / mirror".

Thanks for the report. I will consider this a duplicate of 131736 which is already fixed for 2.1. Reproduction is verified as fixed.
