Increased to 300, not by additional 300.

Previously my full inventory, I counted the current inventory space is 255-ish (before update) . So this week update just increased additional 50-ish . It's too little honestly. Additional 300 will be more helpful with all these new items taking spaces...new ninja packs, Infinite Illusion title item, etc.

Inventory backpack, Ninja Tools backpack, Treasure Map backpack, Ninja Fragments backpack. All these have their own separate inventory space

Some possibility I can think of is :

- Ninja Tools backpack full, when you try to claim all that include items(Ninja tool/Pig EXP) to be stored there , it will still show inventory full notice.

- Treasure Map backpack full, need to use some treasure map to reduce and claim to store new ones.

- Ninja Fragments inventory full, they increase the limit many weeks ago but could be this too if you have excess ninja frags sent to mail.

If either one of those backpack full, claim all will not work. Need all them to have enough space. To reduce Inventory backpack, upgrade all the magatamas and rune stones then open some packs, if your inventory the one is full, maybe you stored to much items and the limit increase is not enough
