Cucuruz Doan's Island - S1-E15
Other mistake: When Amuro rescues the two pilots, he lies them down on the beach, side by side on what initially looks like a single tarp. Which can probably make sense, but when the first one dies, Amuro runs to the second, and now it seems that each had their own fancy beach towel to lie upon, which is doubtful being part of the standard Federation equipment.

Cucuruz Doan's Island - S1-E15
Audio problem: In the faraway shot that follows the slap Rollan gives Amuro for accusing Doan, Amuro's lips move a second before his voice is actually heard. (00:14:00)
Cucuruz Doan's Island - S1-E15
Other mistake: Amuro and Doan come out of the waterfall charging. Doan's Zaku shoulder-rams the opponent with the right shoulder, while probably he should have done it with the left one, spiked. Mistake, it happens. What should not happen is what ensues later; as the evil Zaku falls back, look at Doan's; the moment he starts running towards the downed opponent, the drawing is mirrored, and literally from one frame to the next he switches shoulder equipment (the shield moves from right to left).

Cucuruz Doan's Island - S1-E15
Continuity mistake: When Amuro does the emergency conversion inside White Base, he is then catapulted back into action. Next to him, the Guntank, that was not there earlier. (00:19:00)
Cucuruz Doan's Island - S1-E15
Continuity mistake: After the dramatic fight-winning punch, Doan's Mobile Suit is dripping water in a close-up. The characteristic tubes on the head of the mecha are undamaged, but Doan broke one earlier in the fight, and it's broken again in the epilogue. (00:21:00)
Cucuruz Doan's Island - S1-E15
Other mistake: When Amuro tosses the Zaku in the ocean, its 'eye' is lit, but the Zaku is powered off. (00:22:15)
