| Summary | 0008190: Embark Location has 2000+ Z Levels. Crashes on initial unpause | ||||
| Description | Save can be found here: http://dffd.wimbli.com/file.php?id=9562 I had several crashes when I initially tried embarking here, but it seemed like a promising location so I tried again. After the 4th time it let me embark successfully, but it immediately crashed after unpausing for the first time. Inspecting the area while paused I was able to go down over 2000 Z levels. It was still allowing me to go down, so I never did find out just how far it went before giving up on it. | ||||
| Steps To Reproduce | Download save from http://dffd.wimbli.com/file.php?id=9562, unrar in DF save folder, continue game and unpause. | ||||

Uh, what are your worldgen parameters? |

Hm.... Downloaded your save. Managed to navigate to Z-10000 (yep.... it's ten thousands!). Unpausing cased massive FPS drop (to 2(2), sometimes 0(0) during first 4-5 minutes), and then FPS raised to 35(35). I even think, that lowering GFPS could make it playable.... Well, maybe removing graphics pack... I'm using Starter pack 0.40.10 r1, no dfhack, no additional own changes to raws or configs (clear pack, it's even first run of it). core i3 cpu, one core fully loaded. RAM about 700M on unpause. Trying to designate up/down stairs from z-1 to z-10000 coused RAM to go to 1450M, full 1 core load, but no crash yet (well... this designation takes lot of time). Oh.... It's Win7 for me. PS. It's already 10 minutes, but my mining designation not finished yet... Even think, that I must keep this save for experiments, if you don't mind =) |

How did you even generate a world with that many z levels? |

Curiously, there are a number of feature-*.dat files in your savegame that have the same timestamp as the oldest files, which suggests that they were created during worldgen (and might possibly be related to bug 0005077, though that was fixed a long time ago). I tried generating a few test worlds, but feature-*.dat files never showed up until I attempted to embark, and those would be timestamped at least a minute later than everything else (while yours have the same timestamp, down to the second, of the region snapshots). Loading your savegame and analyzing it in DFHack reveals that it claims to have 14,067 Z-levels, even though there are only 79 Z-levels worth of actual map blocks. After revealing the map (which required a patch to DFHack's reveal command), it is clear that something has gone horribly wrong - for most of the map, the Underworld starts at Z=103 (and extends down to Z=99), but for the rightmost region blocks the Magma Sea and the Underworld apparently overlap, having a large area of open space starting at Z=107 containing globs of magma floating in mid-air above the slade landscape. There's also the oddity that, for those rightmost blocks, the Underworld only extends down to Z=103. This might be related to 0001791 as well. In addition, there's plain "grass" in the caverns (0004013), but that may be a result of other glitches. |
