The size of a debris field depends on destroyed units and the debris factors configured for the active universe. Inter-War keeps fleet and defense debris settings separately, so the same percentage should not automatically be assumed for both categories.
How does this rule work?
The server settles debris as part of the battle result using world-local parameters and the units actually destroyed. The pre-battle cost of a fleet does not mean its full value will become debris.
What exactly does the server validate?
If the universe uses different fleet and defense factors, the composition of destroyed units changes the final field. This matters when evaluating attack profitability and planning how many Recyclers or Giga Recyclers are needed.
How does this affect the mission?
Before a major battle, check the world configuration or values shown by the simulator/report instead of importing a default percentage from another game. The resulting field is collected through a normal Recycling mission.
When does it matter?
This mechanic belongs to world parameters and can be configured per universe. Do not import a fixed value from OGame or another server when the active Inter-War world has its own settings.
Common mistake
When planning, use the data shown in the current universe and current reports. The server-side rule is stable, while the specific factor or limit can belong to that world’s configuration.
