Error when running scenario_runner on a non-full element map

[WindTi]

carla version:0.9.12 scenario version:0.9.13 Before I used scenario_runner, I had already use the python API unload_map_layers operation on the map (Town05_opt) through the client, and got a map with only basic elements, and then when I went to run the .xosc type file, a fault error occurred, resulting in the server also crashed. I noticed that scenario_runner seems to reload the map after loading the .xosc, is the critical error related to this? (it works great in integrated elements maps)

This problem can be reduced to another problem. When I use town05_opt and simplify the map, and then create a new client to connect world, the server side will crash.
