Problem with SDK

[antoineok]

Hello, i tried to add achievements to my mod, so i added them, but impossible to earn them, i always get a HTTP Error 400.

Here are the logs from the mod manager:

[SDK] Registered achievement test (Welcome)
[SDK] Registered achievement test_2 (Not for easily disturbed...)
[STDERR] ddmm-modded:no
[SDK] Achievement test earned.
[SDK] Achievement test has not been registered.

does someone know where it came from?
