How to activate deactivated mesh?

After deactivating a mesh, i used the activate node, but it has no effect. Do i have to do something else to “reactivate” a deactivated mesh?

I figured this out.

Scenario: Setting a looping death animation montage section, in combination with deactivating a mesh/character movement.

Fix: Play a new animation montage to get out of the currently looping animation montage section.
