[Lou] [2.0.15] Railgun is shooting other Railsguns

[Zazuno]

good day.
I built a spaceship where my railguns are constantly being torn apart without me noticing. Then I built a loudspeaker to hear this. Every 4-5 hours one railgun destroys the other.
In this Twitch clip I sold the inserter arm for the ammunition and the other two railguns to recreate this scenario.
The basic problem is that the game doesn't tell me that the railgun that is shooting doesn't tell me that it theoretically hits the other railgun.

I'm having this same problem on a different layout. My railgun isn't destroyed immediately, but the result is the same.

No indication of the potential destruction caused, seems like the minimum range does something weird to the collision calc at least as moving the next turret down one highlights correctly

Can confirm that it is happening to my game as well in version 2.0.24. Railguns pointing diagonally that are right next to each other (but not within each other's firing cones) keep randomly getting destroyed. It's random enough that I have not caught it in the act yet. Platform has also taken 0 damage. This only seems to be occurring going to/from the shattered planet due to asteroid density.

Well, glad I searched a second time before finalizing the post. Also ran into this issue. Just going to move the whole post here and hope I add some useful context.

Version 2.0.23: Railgun turret fratricide from damage outside indicated firing arc

In brief:
In some setups Railguns have a chance to destroy each other, and other buildings, without any indication to the player that something is wrong until supplies run out.

In detail:

When placing two railguns flush and at right angles (see attached image and the highlighted railgun within in specific) all indicators will show that neither turret is in the other's line of fire, as shown by a lack of red marks. As such, I expected they would not do damage to each other.

However, when firing at the extreme angles of it's arc, a railgun round can do enough damage to instantly destroy not only everything everything in it's path, but also objects beside it's path without ever alerting the player that something is wrong. The same effect also happens on the other side, occasionally destroying the promethium filtered express splitter.

Occurrences of the issue are intermittent, netting around maybe 36 railgun kills and 32 splitter kills within 6 hours for a pair of such setups, according to the kills chart. It should be at it's easiest to replicate when allowing railguns a broad range of targets.

While this can be solved by repositioning, the main issue is that the game provides no notice of the problem. At first because the indicator that provides warning while building says nothing is amiss, and later because kills on buildings by one's own turrets do not alert the player to the loss before the turret is silently replaced.

A ghost setup replicating the locations that caused the issue.

Had it happen to me too. Visual guide says they're fine, but they are very much not.

I believe the reason some people are only noticing this issue hours in when supplies run out, is because the "victim" railgun is shooting asteroids that the "killer" railgun would otherwise be inclined to reach for and shoot. The victim runs out first, and the next railgun reaches to the edge of its range, which hits the victim.

from the videos I've seen of this, it looks like the target is being selected by bounding box, but the aim is for center, reaching outside the cone. If this is in fact the case, would it be solved by having it aim at the portion within the cone?

This is happening to me. I'm two hours into a shattered planet run and realized I'm down to 30 spare railguns from 100 after noticing that rail guns were dying right in front of my eyes. Double check the placement, and there are no red overlap markers. So they should not be destroying each other.

I really don't want to have to reconfigure the ship, I have probably 10 to 20 hours in designing, re-configuring and testing my design.

In image: Bottom left most rail gun has not taken damage, it is a spare railgun that was previously damaged but placed in inventory and was automatically placed there when the previous gun was destroyed by friendly fire.

Same issue [2.0.28]. My rail guns are getting destroyed

Happens to me as well, the targeting arc is nowhere near the splitter but it gets destroyed by a railgun shot every once in a while. It doesn't even shoot the undergrounds that are next to it but the splitter which is further away gets destroyed.

The ship is the vindicator in the savefile.
