If a bumper comes off when you attach a trailer in Apocalypter, that can be expected behavior. The September 26 release patch says cars automatically detach bumpers when a trailer is attached; rear bumpers cannot be used while towing because they interfere with the trailer and cause physics problems.

The same official patch announcement says attaching a suspension lift kit automatically detaches the trailer so the connection can be positioned correctly. These two changes are more useful for diagnosing a setup than an old video that shows different attachment behavior.

Avoid losing progress while testing

The developer marks the September 26 save files as compatible. The note about newly spawned items is not an instruction to delete an existing save. Preserve your progress and distinguish an older object from a newly encountered one when comparing behavior.

This page documents the confirmed attachment rules. It does not claim an exact interaction key, towing capacity or universal fix for every trailer. If the symptom falls outside the table, check the latest official announcement before applying a demo-era workaround. The game's public discussion board is an existing place to look for related reports.
