Incorrect Distribution Ditto Nature and IVs for forced-0 encounters

[WildEep219]

Describe the bug For the Ditto distribution, RaidCrawler can report incorrect nature and IVs for at least the guaranteed 31/31/31/31/31/0 and 31/0/31/31/31/31 Dittos. Seed, PID, and EC appear to be correct.

To Reproduce If applicable, please list the steps to reproduce the behavior:

1. Advance date until you encounter a distribution Ditto with fewer than 5 flawless IVs according to RaidCrawler.
2. Catch the Ditto and notice its IVs and nature are different from what RaidCrawler reported.

Expected behavior Ideally report the correct nature and IVs for these special Dittos.

Raid Data For the following raid block: 01 00 00 00 0A 00 00 00 01 00 00 00 07 00 00 00 7C D3 F1 FC 00 00 00 00 02 00 00 00 00 00 00 00

RaidCrawler reports that it is Quirky with the IVs 26/21/04/12/30/25. However when I caught it, it was actually Gentle 31/31/31/31/31/0 (No good Speed).

For this raid block from a separate day: 01 00 00 00 0F 00 00 00 01 00 00 00 09 00 00 00 E4 3A 5A 97 00 00 00 00 02 00 00 00 00 00 00 00

RaidCrawler reports that it is Hasty with the IVs 21/29/07/14/22/01, but when captured, it was actually Gentle 31/0/31/31/31/31 (No good Attack)

Thanks. See if the latest commit fixes it (and doesn't break regular raids) once it's done building.

RaidCrawler reported that this raid block was a Careful 31/31/31/31/31/31 distribution Ditto, but after catching it, it turned out to be Mild natured.

The first two you have are both 1% slots with all 6 IVs fixed. If the calculation is done with all the IV generation, gender calculation, and ability generation skipped, it produces the correct nature. I get both the 0 attack and 0 speed ones predicted with Gentle nature on latest commit of RaidCrawler.

I caught this exact Ditto on a completed game and it was Careful as RaidCrawler predicted. This one is one of the 97% 5 IV Ditto. Do you have the file for the one you caught?

[WildEep219]

I do have the file (attached as a zip because GitHub doesn't like pk9 files).

132 - Ditto - 74312F9D504D.zip

EDIT: NEVER MIND! There was another Ditto with the same IVs and same Tera Type that threw me off. Apologies for the inconvenience.

And Anubis said that this Ditto here

01 00 00 00 08 00 00 00 01 00 00 00 0D 00 00 00 52 2B EA 07 00 00 00 00 02 00 00 00 00 00 00 00

does result in Careful when caught. Are you using the latest passing build? I did push a commit just now but it should be irrelevant to this issue (minor readability changes and Anubis' date advance routine).

[WildEep219]

Nope, just trolled by this raid block in the same batch:

01 00 00 00 07 00 00 00 01 00 00 00 03 00 00 00 F2 E5 FF 0C 00 00 00 00 02 00 00 00 00 00 00 00

PEBKAC error here.

Thank you for bringing up the original issue to my attention though, I'll mark this one as closed for now then.
