I have hit this crash twice now and I think I have narrowed down the cause. It seems that if you are running along, auto-placing power poles (I was using medium poles) and hit a point where the game wants to place a pole, but there is a tree in the way, it crashes. Error given in a debugger is:

Unhandled exception at 0x000007f6e3d0dc5c in Factorio.exe: 0xC0000005: Access violation reading location 0x0000000000000090.

Obviously, I don't have symbols for the executable, but the disassembly is:

Got the same when I run with auto lv1 pole placement, the game crash if at the maximal distance, their an object on the same case where the pole try to be placed. work with alot of object.

Also having this same crash when auto placing small poles.

Trees aren't the problem, i've placed several power lines through forests and it works just fine, but i'm having this problem as well, not just with poles but substations as well. It seems to kick in when the game tries to place the new substation/pole. I've had it happen a few times while i noticed biters were running around. This is a bit of a long shot but maybe it's a problem with the pathfinding trying to access the spot you're building on while it's free, then treating it like free after you build on it causing the error?

Crashed while placing a pole as well, but I have symbol information for the devs:

That address 0x90 sounds like an attempt to access class member through a null pointer.

Ok, i've had it happen 12 times in a row now so i'm providing my savegame for reproduction. Just keep in mind it is not happening 100% of the time, but placing a diagonal line of substations between the bodies of water is crashing a lot, if it doesn't just reload and try again a few times, it should trigger it. I noticed a lot of them happen with biters chasing after me in the path of the placement, which is why i think it might be related to the path finding.

It's 150MB for some reason though, no idea why

Update; running game.killallenemies() did not prevent another crash, probably not pathfinding.

same crash happening to me twice in a short period of time, with the long-distance poles. once in the middle of some trees, once with no trees but biters chasing me (bots zapping them.)

Posted: **Sun Jun 08, 2014 12:04 pm**

I think it crashes when there is an entity where the power pole should be placed.

I wonder if this bug has the same cause. Maybe I'm trying to put down a capsule and there's a reason it cannot be placed?

muzzy, I'm curious, how did you get your hands on the symbols files? Having them on my machine would make bug reports much more useful.

Posted: **Mon Jun 09, 2014 11:53 am**

IVe had this happen a few times while dragging poles at just the edge of my placement range. This bug can be reproduced by dragging poles behind you so far away that pole blueprint oscillates between being whited out and being blue while dragging. This crashes me every time.

the mac build just happens to have symbols still in the executable

PS. noo don't remove it devs, I like having symbol information!

Posted: **Tue Jun 10, 2014 1:46 pm**

Thanks for the report guys (including very precise analysis of what is going on

). This will be fixed in the 0.10.1.

PS. I was not aware that we have symbol information included in the binary. I will discuss leaving it there with others - especially seeing that it has been useful for you guys to pretty much come up with the solution to the bug report.

Definitely makes sense for a beta version. Maybe DICE should consider the same? :-D
