imncremental training NullReferenceException after last update

[bill3code]

Hello!
After the last update, I get this error:

Необработанное исключение: System.AggregateException: Произошла одна или несколько ошибок. ---> System.NullReferenceException: Ссылка на объект не указывает на экземпляр объекта.

before update it is working without problems.

My config is :

`CURRENT_DIRECTORY = .\model2cfg

MODEL_TYPE = SEQLABEL

#Forward and BiDirectional are supported
NETWORK_TYPE = Forward

MODEL_FILEPATH = model.bin

HIDDEN_LAYER = LSTM:200, LSTM:100

OUTPUT_LAYER = Simple

CRF_LAYER = True

TFEATURE_FILENAME = tfeatures

#Binary and Freq are supported
TFEATURE_WEIGHT_TYPE = Freq

TFEATURE_CONTEXT = -7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5

PRETRAIN_TYPE = Embedding

WORDEMBEDDING_FILENAME = vector_big.bin

WORDEMBEDDING_CONTEXT = -1,0,1

WORDEMBEDDING_COLUMN = 0

AUTOENCODER_CONFIG = D:\RNNSharpDemoPackage\config_autoencoder.txt

#SEQ2SEQ_AUTOENCODER_CONFIG: D:\RNNSharpDemoPackage\config_seq2seq_autoencoder.txt

RTFEATURE_CONTEXT = -2,-1`

This happens after 47 iterations...
