Evolutionary tree not working

[AIKO]

randomly during a playthrough the evolutionary tree stopped showing and it told me to send a bug report, so here we are.

Thanks for the report. Here’s the relevant error from the logs:

Do you have a save file from when this happened? It might have some useful extra information.

This seems like a new error so I’ve opened an issue:

Evolutionary tree can stop working due to "World history is out of order"

So, @AIKO , do you have a save-file from when this happened? It’d be very appreciated if you shared it. You can embed it into your google disk and make the save-file public via a link, and then post the link to the file here.

i think i figured out the save thing, here you go.

For some explanation, I was using experimental features with it, (forgot to add this) and it was probably why something broke.

To my awareness at the present the experimental features only encompass the siderophore feature (for iron organelles), so not sure if it actually has to do with the mode.

Thanks.

With that I was able to investigate the problem and found out that rather than things being in the wrong order, your world data is missing generation 13 for some reason. There is no code in the game that should delete any generations so the generation must not have been created in the first place for some reason.

I can’t make a proper fix for this, however I was able to come up with a workaround that makes malformed generation histories like this be able to display the evolutionary tree (but obviously the column for generation 13 is just completely empty).

Added safety handling for missing generations for evolutionary tree

Thankfully more workarounds won’t be need pertaining to missing/“removed” generations.
I wonder just how many “improper fixes” will we have by the end of Microbe stage development…
