[BUG] Custom checkpoint not triggering

[mGuy]

Heyaa,

While making RPG map (rpg titlepack), I've encountered weird bug (or not?) concerning custom checkpoint item I've made. Both geometry layers are using TIAdd materials I don't know if I've done something which can't work for CP or not, please tell me if i did. There's nothing much to say, everything is shown in this video :
