[Suggestion] Make Halloween Monster Sacks useable in towns and "non-mob" maps ONLY

I am suggesting that the new monster sacks that are a reward from the "Trick or Treat Box" from the halloween event should be made so that they can only be used in towns or other maps that are "non-mob" (aka maps that are not used to train). These sacks are primarily only going to be used to grief and troll other users by killing them while they are afk. The sacks currently can not be used in the FM and I suggest that effect be brought to training maps (if possible).

Event has been out for 24 hours now and I have already seen smegas of people using them to kill leechers and afks (not going to mention names). I feel like this will cause a lot of drama and issues between those who sell and buy leeches if sacks are allowed to be used in training maps that are used to sell leech (ex. Wolf spiders, petris, skeles...).

Sacks were already removed once from quests in the past, also curious as to why they are back now and why they were removed in the first place (what has changed since?).

Open to any and all feedback! Thanks!

EDIT: This is not a thread to have monster sacks removed, it is a thread to have them changed. Please do not be confused.
