Shadowbrine1, i do this bug completing level in practice mode, after completing in practice mode i hold checkpoint place button and after this i can place 1 checkpoint in normal mode, if i release left mouse key, checkpoint will be placed.

I found this bug when i was playing levels in Geometry Dash.

With this bug enabling player control in normal mode when it's disabled is possible but you can place only 1 checkpoint in level.

This bug works on PC and Android

This bug works on versions since 2.2 (it works on 2.206 too)
