If I try to open the GUI on a saved game that already had the mod, it crashes

2531.321 Error MainLoop.cpp:850: Exception at tick 46338510: Error while running event BotStats::open_gui (ID 79)
BotStats/control.lua:74: attempt to perform arithmetic on global 'update_ticks' (a nil value)

Thank you for the report.

I think that I have fixed this issue. Please let me know if you encounter it again.

Working nicely now :)

I know I am being annoying but... I really got used to see the number of 'free' bot and not the ones in use.
Any chance of a setting to choose which one should it show?

Thanks for the update. Helping me to discover bugs and providing useful feature requests is not annoying. :)

I'm kinda torn on the usefulness of showing available bots since you can just mouse over a roboport to see that info. In the meantime, you can edit the control.lua to make it so. Just remove the subtractions on lines 84 and 85 leaving just the available_xxx_bots variables.
