Regarding refuelling, please take the following precautions.
Fuel loaded is higher than fuel requested. For example, if you request for 25% of fuel, you will get around 43%. We are investigating what can be the reason for this behaviour.
Since you can't load more than 97%, the loading event will never end, unless you start moving so that mechanic and fuel track get disconnected. Therefore, take into account that you should request first weapons load and then fuel load, once weapons are loaded, otherwise the weapons loading event will never start since fuel loading keeps in progress for ever.
We hope to be able to solve all this soon.
