<p>tldr;<br>
The translated entity was never updated on save after upgrading module to alpha3.</p>
<p>When updating a translation for a block_content, the translated content did not appear on the translated entity but appears on the original source language entity instead after saving it. This happens on translatable node content types as well.</p>
<p>The root cause is happening from conflict_entity_prepare_form line 118, where it overridden the entity set within form_object, which is further used by content_translation module on content_translation.module line 391 to retrieve its entity object again and down the line it determine the active langcode to update the target translation of the entity being saved.</p>
<p>In short, the entity fetched from conflict_entity_prepare_form has an activeLangcode = "x-default", while the translated entity should be saved has its activeLangcode = "en" (when x-default langcode being zh-hant), the latter was overridden by "x-default".</p>

<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Rewrite conflict_entity_prepare_form to respect and set the translated entity in its form_object.</p>
<p>P.S. We downgraded our module alpha2 temporarily before this issue is resolved.</p>
