So I decided to make an account just to report this.
I've noticed at least two bugs in the following battle:
http://replay.pokemonshowdown.com/gen4ou-414139288
#1. My Sudowoodo's sturdy ability didn't activate when the opponent's Metagross hit it with a Meteor Mash, resulting in a OHKO. I did a little research after the battle to ensure nothing went wrong and that I'm not crazy, such as looking at Metagross' ability to ensure that it didn't contribute to Sudowoodo's OHKO, but no - Sudowoodo should have lived through it. I'm not sure if all Pokemon with the sturdy ability have this problem at the moment or if maybe it's just a Sudowoodo thing. Nonetheless, I ask that you take a look at this.
#2. In an effort to speed through the battle to get this report to the forums, I randomly had my Togekiss use defog while Stealth Rock was set up around the field. It did grant the evasion debuff, but it did not remove the traps from the field like it's supposed to.
- As a side note, there was another battle where I encountered the same scenario - unfortunately, I do not have the replay for it.
Anyways, Spikes were set up around the field this time and once again my defog didn't get rid of the traps around the field. Rapid Spin
seemed to do what it's suppose to do later on in the battle, but defog didn't.
Please note that this recorded battle took place in the Generation 4 OU. I used the same exact set in the Generation 5 OU, and I can confirm that bug #1 is present there too. I'm not sure if defog is broken over there, though. Thank you for your time.
