Need some help

so i have lost data on several world maps i have built and had to start from square 1. i would like to see if there are any assets i can get that would help cut my development time down a bit so i can get back on track. i use synty studios assets and i would like to see if there is an asset that would help in the aid of building a city that i can use and edit. i want to get most of it there so i can add roads and adjust for loot and stuff. thanks in advanced. 4th try is a charm. lost years worth of building and development.

 

Always back up your project!. Ive seen many probs like importing assets, and changes that can kill a project. Back up, or use a form of source control, you could have saved all that work. Sorry to say, but a hard lesson to learn...
