uhh why would you want to uncheck read only?
after all blockland reads the addons and possibly places it in some temporary storage for the code/script and textures + models shouldnt be read n write but just read, because once you change anything related to textures or models | blockland wouldnt be able to find the changes properly unless you have already spawned the item/weapon/vehicle/static shape so that itll load its necessarities and ignore the folder contents packaged for it
and for handling script/code edits, it handles through blockland's already executed script/code so its technically read and write... through i doubt bl allows the datablock's shapefile to be swapped in mid-game
