Hi,
I am playing with TradeRouteOverhaul modified for mods usage, This mod creates Assembly machines and lock them with various recipes. In a city like fashion.

I have traced this bug with using only the required mods you need plus the TradeRouteOverhaul mod. And got this even from the starting new game.

Your 0.24.0 version does not interfere with this mod.

The mod Colonists (0.25.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Colonists::on_tick (ID 0)
Colonists/prototypes/housing/housing_script.lua:223: attempt to index local 'player' (a nil value)
stack traceback:
Colonists/prototypes/housing/housing_script.lua:223: in function 'update_working_colonists'
Colonists/prototypes/housing/housing_script.lua:379: in function 'handler'
core/lualib/event_handler.lua:47: in function <core/lualib/event_handler.lua:45>

Could you try 0.26.0 please? And let me know?

The answer is Yes and no.

New game Worked with Colonist (0.26.0) with my TradeRoutes
New game with all of my mods active Worked.

My existing savegame with all the mods Failed to load. There was i think somewhere else non-recoverable error.

But i will call it success for now.

Thanks.

I did get some errors with TradeRoutes but didn't investigate further

Original TradeRouteOverhaul blocks mapgen, research and mods as a whole.

Because i have disabled the blocks and some fixes elsewhere to work. Here is my changes if you want to play with unlocked TradeRoutesOverhaul
