@Vanamonde well, you can't wait for it as such. When you hit space to deploy the module, it starts floating toward the surface but fails before it gets there. It does get to the surface but only after the deployment has failed and there is no way of re-deploying without picking it up, and then you have the falling problem again..
Error just after deployment...
