Anyway, how did you compute the 9% probability. Using formula from http://preshing.com/20110504/hash-collision-probabilities/ : (1-exp((-20*19)/(2*2^32))) multiplied by number of players I can get approx. 4.2%. Am I doing something wrong (yeah, probabilities are tricky)?


I was wondering the ...

As a software developer myself, I expect the underlying APIs, frameworks, and yes - networks, to behave they way they are supposed to behave.
Really?
In the years that I'm a software developer I've learned most but not all APIs, frameworks and networks behave the way they are supposed to behave ...

I included a screenshot and I also included the packets that are being filtered, so maybe you can ask your ISP a few questions of why they are filtering those specific packets.

I re-calculated the checksum both for the first large packet and the small packet. They both (should) have checksum ...

Both 508-byte packets do have the same checksum:

$ cat pkt1.dat | od --endian=big -w2 -An -tu2 | awk '{sum += $1} END {print (sum + rshift(sum, 16)) % 65536}'
24005
$ cat pkt2.dat | od --endian=big -w2 -An -tu2 | awk '{sum += $1} END {print (sum + rshift(sum, 16)) % 65536}'
24005


I tried ...

The crash still exists in 0.13.7, but the behavior got worse. Now instead of simply crashing and exiting, the game's CrashHandler now crashes in an endless recursion. The game needs to be killed manually with "kill -9".

I am running version 0.13.6 of the standalone (downloaded from http://www.factorio.com) game on Linux.

The game crashes reproducibly upon attempting to join or leave a multiplayer game. This crash only happens if I run Factorio as a background process, then closing the terminal window:

The car in New Hope level-02 starts with a stack of 64 coal in its fuel tank. Normally coal has a stack size limit of 50.

I also looked through the rest of the New Hope levels for related errors, and noticed that the level-03 starting inventory includes 128 each of fast belts and stone walls. These ...

Same here, Ubuntu 16.04 beta, 64-bit. Purchased the game through steam, and linked it with a factorio.com account. I get the error even when I try to hit the get-token API directly.
