Needed:
Dedi/Local Hosted MP game
Two playable units, A and B

• In the init of unit A (via Editor):
this addItem "FirstAidKit";

♦ Now start the mission, you'll see that one first aid kit
was added to unit A.

Things are getting interesting in the next step:
JIP with player B. Observation: player A now has two first aid kits because on the JIP of player B, player A's init was executed again or so.

It seems as if the same thing goes for the "hint" command.

No DEV. It's important that especially ITEMS added via the init box of a unit are getting duplicated upon JIP.
