Hey everyone,

I have more content fixes fresh from the oven and mixed with あんこジャム so you know they're good.

This patch is mainly typos and kanji fixes:

Formatting / Typos

• Fixed a potentially confusing double negative in an explanation in Unit 108, ます-stem に行く lesson.
• Fixed a missing せ in an explanation in Unit 98's lesson "Verb stem changes"
• The translation of the わたしは一度、ヘリコプターに乗ったことがあります。 sentence was missing an "in". (Is now "I've ridden in a helicopter")
• Fixed a typo in an English explanation in the "お～ください" lesson. (here → hear)
• Fixed a typo in the "Words and phrases related to New Year's" lesson.

Content Fixes

• Removed the ゆう reading from the Onyomi section on the 夕 kanji flashcard. (Onyomi reading is セキ)
• Fixed wrong wording in the Summary of Phase 2 Unit 32's "Requesting and receiving things with ちょうだい" lesson. (be followed by → follows)
• Fixed a wrongly split literal breakdown in the sentence "この上着を着てみてもいいですか。" (みても → みて　も)
• Fixed a missing element ("one") in the 写 kanji flashcard.
• Fixed missing elements and mnemonic for the 号 kanji flashcard.
