Describe the bug

After I updated the server from version 1.2.0 to version 1.3.0 Airdrops are not working anymore. Everytime, an airdrop is supposed to come in a console error is generated.

Steps to reproduce

Update Server from 1.2.0 to 1.3.0 with overwriting existing files from downloaded update.

Expected behaviour

I guess airdrops should spawn and land properly. :)
