What happened
The July 12 hotfix temporarily made players unable to capture Tramplers while the team works on reliable protection against no-clip and teleportation cheats.
Why it matters
The hotfix disables the capture action itself, so repeating an older capture route cannot make that action available while the restriction remains.
What to do next
Stop retrying the older capture flow. Check the official announcement feed after any newer update, then retest before relying on Trampler capture again.
