set_value() in CI3 has issues with input arrays

In Codeigniter 2 our forms were able to have

PHP Code:

<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />
<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" /> 


and each one would be populated from POST without an issue. With Codeigniter 3, all our forms that did that are now broken and I have to manually put in [0],[1],[2],etc for each form field's set_value(). Was this an intentional change or am I missing something that needed to be changed from CI2 to CI3?

The error

PHP Code:

A PHP Error was encountered
Severity: Notice
Message: Array to string conversion 


I did look at the form_helper from CI2 and I saw it parsed out the values if it saw an array and returned them differently than they are being done in CI3.
