Summary

I was coding carpet system for houses and I discovered that there is something wrong with how they are being placed in stack

Steps to reproduce

create two carpets on same tile:

1. /i blue carpet
2. /i brown carpet

Expected behaviour

brown carpet on top

Actual behaviour

blue carpet on top

Another example:
placing two carpets in a house

after saving and restarting:

they get flipped every save+restart

I can confirm that this bug is indeed existing.

potential fix for house loading (needs testing):

forgottenserver/src/iomapserialize.cpp

Line 144 in c274252

parent->internalAddThing(item);

-				parent->internalAddThing(item);
+				parent->addThing(item);

how this work with more carpets?
maybe we can use this behavior for "random houses", after each ss we can take top one and move it on bottom (ofc enabled by config)

well, you can (should) only put 3 carpets on same sqm, and they should keep the stack order that you added them, this is a very weird bug

It's a bug. Rather small sample size, but 3/3 of my testers arranged their carpet stack and found this annoying.

Answering the other question (can't quote because I'm on a phone) the placing script limits the carpets.

@ArturKnopik maybe u understood that this is a bug in a house, but this bug happens everywhere, not only in houses. Should be fixed, not implemented as a feature.
