1) You can stack 25 item that take 4 slots.
if you want to do a shop:
- place your money in your bank, you never know, a bug can happen quickly ^ ^)
- Place your 25 steel (for example) in your inventory and open a shop.
- If you're dc relaunch the game without activating MTB and reopen your shop. Your 25 items are still stacked in your inventory and u won't be dc when u'll open ur shop.
2) The bot does not work, the tab was displayed by mistake, but the functions are inactive.
Hope that help
