On CptCanada YouTube prerelease of the A350 from iniBuilds yesterday while using Navigraph for the in-sim data, he was getting consistent freezes of the sim while at KATL and setting up the flight plan. Everytime he selected runway it would freeze up the sim. Even importing via Simbrief did not work. It was only upon going to another airport was he able to get it to work.
He was using the KATL from Imaginesim.
Are you all aware of this issue with KATL nav data giving a WASM crash? This was on MS2020.
