 Etoys 3.0.2159: Make a script like

 {{{o's direction <- o's direction + o's direction}}}

 and notice the left+right-pointing arrows (green triangles) at the end of
 the expression. Now switch language, e.g. to German ("Deutsch"). The
 arrows disappear.

 Now drop another line into the script. Right-pointing arrows are added to
 all tiles, but no left-pointing ones.

 The expected behavior would be that switching the language does not affect
 the arrows. The current behavior is particularly annoying when loading a
 project authored in a different locale, which is the case for most
 projects on the web.
