i noticed two bugs happening in multiplayer where the client is not able to collect from resource dispensers or pick up resources that have been dropped by himself because the backpack was full.
1) Sometimes the client is not able to gather resources from the dispensers. The animation is playing and energy is used but the resources are not collected.
2) If a clients collect resources and his backpack is full the resource is dropped on the ground. The client is not able to pick this resource up. The server is able to pick them up. If the client leaves the area and returns later the resource is gone (for the client) but still visible for the server.
