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.
