Description
Hi All,
I need to merge 14 vector layers then I tried to use saga merge vector layers to do It
when I run It, It came out with the below error log:
2018-03-26T16:35:54 CRITICAL Traceback (most recent call last):
File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\algs\saga\SagaAlgorithm.py", line 231, in processAlgorithm

append(deepcopy(a, memo))

rv = reductor(4)
TypeError: can't pickle QgsVectorLayer objects
in QGIS 2.18, it works fine with the same files an the same SAGA version 2.3.2
