Error while running event ColonyBuilder::on_nth_tick(36000)
value for required parameter 1 (surface) is missing

Do you use any mods that alter, create or delete surfaces in any way? Not exactly sure what causes this but I may have a fix in the next patch, if its not fixed in the next patch let me know.

Hi.
Hard to tell as I have many mods.

After a while, now when I try to start a new game with Colony Builder activated, I get this:

Error while running event ColonyBuilder::on_init()
core/lualib/production-score.lua:50: table index is nil
stack traceback:
core/lualib/production-score.lua:50: in function 'get_product_list'

Are you by any chance running the "Cerys, Moon of Fulgora" mod? The same error has been reported in: https://mods.factorio.com/mod/ColonyBuilder/discussion/676a58d59092b02711e000f4

This error is caused by a vanilla Factorio script that I use to calculate prices for items. I am not going to alter or copy this script.

Yes, I do have those too.
So, I guess they aren't compatible at all. Sad.
