Does not work

[intek71]

Please, help - cant seem to firgure out what I am doing wrong:
using this seed phrase:
ceiling luxury void exotic thunder stable very type tree fruit custom material social muffin pumpkin clog actress wolf bamboo ecology replace runway curtain hollow

keep getting Invalid Mnemonic

[iancoleman]

The checksum of the mnemonic isn't valid.

For example, a very similar mnemonic with a correct checksum (last word) would be

ceiling luxury void exotic thunder stable very type tree fruit custom material social muffin pumpkin clog actress wolf bamboo ecology replace runway curtain glance
