im playing a many islands map so this mod is vital but i had to disable planet pelagos due to cargoship tec being blocked by a long line of space travel tec can you add an option to disable space and decomp bottle requirements and return it to its old tec tree position after engines after disabling pelagos mod i cant seem to find cargo ships in the tec tree not sure only the oil tanker and the tugboat

Those changes are made by the Pelagos mod. The author of that mod insists the tech tree changes and surface limitations are vital to his mod. Someone made a tweaks mod to undo the changes, and he marked the tweak mod incompatible. You will have to take it up with them or uninstall Pelagos.

Edit: just realized you already disabled it.

disabling pelago caused severl issues with cargo ships primarily the water transport tec is gone and cant be researched resulting in the entire mod being locked by hidden tec overseas poles tec is also missing from the list the beter option would likly be starting the game with out pelagos mod then turning it on after all the ocean world tec is unlocked im gona test tat theroy

tested and thats the best option so far but im not liking the idea of having to start over

If you haven't built any cargo ships yet, you could also disable cargo ships, load and save the map, then enable cargo ships again.

Or you can send me the save and I'll figure out what console commands will fix it.

/c game.player.force.technologies['<RESEARCH-NAME>'].researched=true
but it disables achivements si i just started a new game i didnt get to blue science yet anyway since oil was inaccessable

It's very weird that it happened, because Factorio is supposed to rebuild the technology tree any time a mod is added or removed. But glad you are back to playing again.

Okay, if anyone runs into this in future there is a solution. Talandar has programmed a lua script to crash your game if you try to modify the recipes, but you can resolve it fairly easily.

1. Open the Pelagos zip file, and open control.lua in a text editor. Find the line "local function sanity_checks()", and delete everything between it and "end", you want it to look like this:
   local function sanity_checks()
   end
2. Save the modified file, and hit yes to update the archive if prompted.
3. Once that's done, install this mod. It should revert all the research and recipes back to their vanilla state.

I expect he will modify the script at some point to make this more difficult, but it should still work as of 0.59.0.
