Bad SP Quake bug in Darkplaces (can't beat game)

[Mr. Shickadance]

I know this isn't the place to get detailed technical help, but I have been experiencing a game-breaking bug while using Darkplaces to play single player Quake. Basically my collected runes disappear at certain times. This means that I'll complete an episode and go back to the start map only to find other previously completed episodes open. And of course my inventory shows the runes as missing.

This has been driving me insane because I have been trying to find exactly what triggers the bug. I have even began swimming through the source code but without any previous exposure that has been difficult (BTW, if anyone knows what data structure the collected runes are stored in I'd like to know). I just wanted to see if anyone else has experienced this as well.

I am still not exactly sure what is happening, but I had a game saved with episodes 1 + 2 complete. I was in episode 3 and purposefully died. I just clicked the mouse to respawn at the beginning of the level and my runes were missing. I can replicate this, but I am not sure if this is how it happens every time.

Also, I am running on Linux but I highly doubt that is related. I have tried compiling the engine myself but I can't seem to figure out where the collected runes are stored. This code certainly isn't very self-documenting as they say.

Thanks for looking!

Well, I finally beat the game. However, I did type 'impulse 11' at one point to give me another rune (the 3rd one). I then finished the 3rd episode and got it anyway. Proceeded on and finished the rest of the game.

I know there is some sort of issue, but I am having a hard time figuring out the exact circumstances that cause it.

Something similar was reported in the todo file:

f bug darkplaces server: losing runes on episode completion, completing episode 1 then 2 then 3 causes it to forget 1, then 4 causes it to forget 2 and 3, making it impossible to open the boss gate (James D)

The 'f' at the beginning indicating it was a failure. :p

Hmmm never had this issue when playing offline (haven't online co-op). Maybe you have the game set to online (hosting a server for others to join) when playing?

[Mr. Shickadance]

Hmm, that sounds strange. How could I check for it?

Unfortunately I have save game problems with Quake 2 as well. The best running client (AprQ2), will simply not save and restore games correctly.

This is an old bug that (I believe) is not DP-specific, that causes runes to disappear if the game is saved somewhere other than on the start map.
