CheckSumWrongException: hash checksum failed

[BullyWiiPlaza]

Downloading decrypted FST entries does not work with the latest commit hash 15a1df1:

val downloadsDirectory = Paths.get("Downloads");
Files.createDirectories(downloadsDirectory);
val commonKey = StringToByteArray("...");

val titleId = 0x0005000E12345678L;
val titleIdDirectory = downloadsDirectory.resolve(Long.toHexString(titleId).toUpperCase());
Files.createDirectories(titleIdDirectory);
val nusTitle = NUSTitleLoaderRemote.loadNUSTitle(titleId, commonKey);

val fstDataProvider = new FSTDataProviderNUSTitle(nusTitle);
val decryptionService = DecryptionService.getInstance(fstDataProvider);
decryptionService.decryptAllFSTEntriesTo(titleIdDirectory.toString(), true);

Exception:
